Fire Sprinkler System Test Form Blaine

I did not hear about that particular incident nor know any specifics, but my engineering experience has me thinking of the following possibilities, all of which have a common flaw:In order for the sprinkler system to be activated, a sprinkler head had to have been open, either by being heated to the point that its fusible link melted, or was damaged by being struck by some object.When sprinkler flow is activated, a flow switch closes to send an alarm that flow is occurring and to alert authorities. When testing a sprinkler system, a valve is opened to mimic system flow and the alarm operation is observed and confirmed. This is true of almost all water-based fire suppression systems.I cannot think of a condition where the TESTING of a sprinkler system would have caused a sprinkler system to discharge water, unless a sprinkler head was already open. So I am thinking this system was a pre-action type system, described below.Understand that there are three most-common types of sprinkler systems, wet, dry and pre-action.A wet system is the most common, we all see them nearly every day in commercial buildings. The pipe is filled with water, ready to go. A fire will melt a fusible link on a sprinkler head, the water comes out, sprays outwardly and suppresses the fire.A dry system is second most-common and is used where the pipe system is subject to freezing. An open parking garage is one example. In this case, the water main feeding these systems has a check-valve that allows water to flow only in one direction. The piping is filled with gas under pressure, usually compressed air but sometimes nitrogen, to a higher pressure than the incoming water would be. This keeps the check valve closed and the water out of the piping.When a sprinkler head melts and opens, the dry gas leaves as the water rushes in, to suppress the fire. Only at that moment does it become a wet system.A pre-action system is a subset of the dry system category. It is a dry system that requires at least two and sometimes more conditions to activate. For example, the activation of a sprinkler head, activation of a heat detector or a smoke detector, or both. Pre-action systems are usually used in archival storage vaults, museums, data centers and other places where water alone could cause a lot of unnecessary damage, even by accident. In a pre-action system, when a sprinkler head might be damaged, no water will come out. No harm, no foul. A drop in pressure will send an alarm to say something is wrong, that the pressure charge is lost. No water damage to the protected materials due to a false alarm.If the sprinkler head fusible link had melted due to a fire condition and, say a smoke detector or secondary heat detector also was activated, then an automatic valve would open. This would fill the system with water and thus out to the open sprinkler head(s). This indicates a real fire is occuring and water damage becomes a least concern at that point.Because the wet and dry systems did not discharge water immediately, the testing of a pre-action system would introduce flow to the system and thus the space.Again, purely conjecture of most likely causes, without better information.

As a pharmacist ( granted, a retired one )…I believe I can give you the best, straight to the point answer you require. If you are trying to pass a UDS ( Urine Drug Screen ), and only a UDS, without popping positive for …there are actually two proven ways to do this. The first ; Find a psychiatrist who will prescribe for your ADHD. While is not exactly ( it can be argued that it could qualify due to some of the short chain molecular properties ), it IS definitely an amphetamine. And, in UDS's…they look for the broken down metabolites of amphetamines. If you have a prescription for …you have a pass.Second ; The trick to all UDS's, is that they all test by looking for…or reacting to ( just like a litmus test ) a certain amount of those metabolites in your Urine. And, of course, they want that test to react to as FEW as those metabolites as possible. We're talking down to several “ Parts per Billion “ !! So, how would one make their Urine contain as few metabolites ( parts per billion ) as possible…in essence making there Urine as clean as possible ?? Simple…You flood your urinary tract with as much water as possible !! About an hour before your test, begin drinking from a gallon of water, one 8 ounce glass every seven minutes for around 30 minutes. ( At this time, you will begin to urinate quite often. Good !! That is the key !! You want your Urine to be flushed out of everything that was hanging out in your urinary tract !! ) For the last 20–25 minutes…drink constantly. Don't try to finish off the gallon quickly…because you'll stop urinating, and those metabolites will gather again. No…drink steadily and constantly, all the while urinating as often as possible.Now, if you are in Pain Management…this might not be the solution for you. For while you may show no metabolites…you will also show no metabolites of the medications the Dr. has prescribed you for pain !!This WILL work in any other situation. Good luck !! ( I would suggest not indulging for at least 24 hours before hand. Oh, and many labs and tests look for the ingredients in those herbal teas…i.e. Goldenseal )

On average, the cost of a residential sprinkler system is currently $1.35/ square foot for new construction. So on a new 2,000 square foot home you would add $2,700 to the cost.Source: Frequently Asked QuestionsThe cost is much lower than commercial sprinklers because residential systems can use PVC piping instead of copper or steel.No statistics are kept for retrofitting sprinklers into existing homes because the cost will vary widely depending on the type of construction involved. For example, an older house with plaster and lathe walls and ceilings will cost signNowly more than one with sheetrock surfaces.

Okay, here's the thing: we are dealing with some very complicated stuff here. I once spent an entire summer internship programming a simulation of water droplet (and water droplet-sized ice crystal) motion in one dimension, although to be perfectly fair, the simulation was primarily built to examine heat transfer into and out of that droplet. To be even more fair, the heat transfer mby tatters in this scenario.Layman's terms aren't going to cut it if you actually are looking for an accurate answer. Having said that, if you're just looking to understand the basics of how one might start looking for that answer, well, that we can work with. We'll build this model up slowly.Simplest ModelApproximate Difficulty: High school physicsOur sprinkler is going to be stationary, then fire off a small steel ball. This will happen in a room with no air. Newton's First Law of Motion states that an object in motion will remain in motion and an object at rest will remain at rest unless acted upon by an unbalanced force. In other words, things keep moving in the same direction until they are forced to stop.Our sprinkler fires things off in two directions: upward (we'll call that the z direction) and away from the sprinkler head parallel to the ground (the x direction). Now, we know that gravity is going to act on the steel ball. Gravity pulls things downwards, and downwards is the opposite of the z direction. We'll call that negative z. In other words, at some point, the ball is going to stop going upwards and start going downwards, and then it's going to get faster and faster as it goes down.This is called acceleration due to gravity, and it happens at a constant rate. So while the ball is not moving downwards at constant speed, the rate at which its speed is changing is constant. And as Galileo proved, the mass of the ball doesn't change that rate of acceleration.But what about the ball's speed in the y-direction? Gravity doesn't act in the x-direction, so whatever speed the ball starts with in the x-direction, it will end with in the y-direction. To get the distance the ball covers in the x-direction, we multiply that speed by the time the ball is up in the air. We figure that out by figuring out how much time the ball would take to fall to the ground if we just threw it up in the z-direction with the same initial z-direction speed as the sprinkler imparts without any x-direction speed on it.Adding RotationApproximate Difficulty: Still high school physicsLet's now start spinning the sprinkler. Now when the ball is fired off, it starts travelling in the z-direction (up), the x-direction (parallel to the ground, away from the sprinkler) and also the y-direction (parallel to the ground, in the same direction that the sprinkler head is travelling when the ball is fired.) If we know the distance from the sprinkler head nozzle to the axis it rotates around and we know how many times per second the sprinkler head rotates, then we can multiply those two things together and get the starting speed in the y-direction.Gravity is still the only force acting on the steel ball. That means the x- and y-direction speeds are unaffected. Again, we can figure out how long the ball is in the air, so that means we can figured out how far the ball travels in the x-direction and how far it travels in the y-direction by multiplying the initial speeds in those directions by the time spent in the air.Putting Some Air in the RoomApproximate Difficulty: University student with a lot of time on his or her handsNow we're starting to deal with aerodynamics. There are four forces to deal with in aerodynamics:-Thrust, which moves you forwards-Drag, which pulls you backwards-Lift, which pulls you upwards-Weight, which is gravity, which pulls you downwardsThe droplet is not pulling itself forward, so there's no thrust. We already know how to deal with weight. This leaves drag and lift. Lift comes from air being forced downwards by whatever is traveling through the air. Scientists don't fully understand how this works with baseballs, but it can be modeled in wind tunnels.This gives us two forces in the z-direction: one in the positive z-direction (upwards, that's lift) and one in the negative z-direction (downwards, that's weight). The weight of the ball is not going to change. The lift may. So from an instant-to-instant basis, we need to figure out what the net force is in the z-direction. Divide that by the mass of the ball, and you have the acceleration of the z-ball on an instant-to-instant basis.Now we get to drag. Drag is the force that resists anything from moving through the air. So if you're moving through the air in a positive x-direction, drag will pull you in the negative x-direction - ditto for the y- and z-directions. This means that drag will affect how fast the ball is moving in all three directions.Drag relies on the shape of the object moving through the air as well as the speed at which it is moving through the air (so does lift, for that matter). This means the force of drag in all three directions is going to change constantly.And both lift and drag, it should be noted are calculated using the speed of the object traveling relative to the motion of the air. If the air is perfectly motionless, we're probably going to have the easiest time with calculation. If the breeze is constant, that's second easiest. If this is outside, this is not going to be easy.(If you're dealing with stationary air, you might be able to do this with a pencil and paper, so long as you're not too picky about precision. You're better off using a computer.)Steel into WaterApproximate Difficulty: Grad schoolRemember how I said heat exchange matters? Here's where that comes in.When you sweat, it cools you down because, even though the sweat isn't at 100 degrees Celsius, part of it does still evaporate. And in the case of dew, moisture in the air will condense on an object that isn't the atmosphere. This means that, when we fire a water droplet through the air, it is constantly changing size and mass. How quickly the water droplet grows or shrinks relies on a variety of factors including:-the temperature of the water droplet-the temperature of the air-the humidity-atmospheric pressureSo now, drag and lift are constantly changing not only because the speed of the droplet are changing, but also because the size and mass of the droplet are now also changing. Also, it should be noted that, as a result of the condensation onto the droplet (or the evaporation from it), the temperature of the droplet, the temperature of the air, the humidity and the atmospheric pressure are also changing. In other words, the rate of condensation/evaporation is changing.In other words, calculating the acceleration of the droplet in all three directions is now an unholy mess and you're going to use a computer to calculate it. Writing the program to do it is not trivial - again, doing this for one dimension without gravity took a fourth year university student a summer.(Just a word of warning: if you fire these droplets into subfreezing temperatures, they will not freeze when they hit 0 degrees Celsius. They will get to some much lower temperature - max is around -50 degrees Celsius, as I recall - then will partially freeze and have their temperatures rebound back to 0 degrees Celsius. Literature on this phenomenon is scarce.)Multiple DropletsApproximate Difficulty: I don't even... look, just... no... (Harold goes off to cry)So we never have sprinklers firing off one droplet at a time. If there are two droplets, they'll affect each other based on the evaporation/condensation deal mentioned in the last section. Which means that now we have to keep track of all the salient details for thousands, if not millions, of water droplets.And that's not even getting into collisions. Wouldn't it be nice if they just smacked into each other and then merged perfectly? Yeah, that's not how it works. Modeling water droplet collision alone is a heinous amount of work. It's theoretically possible to do this, supposing you have a very fast computer with a whole lot of memory. I wouldn't recommend trying it.Bottom line: if you're looking to figure out where best to place your sprinkler to best water your begonias, experiment, don't model.

By drinking an exorbitant amount of water my friend. Let’s say you’ve got to test on this Friday. Today is Monday. If you begin cleaning up today and remain COMPLETELY abstinent from ALL drugs and do the following, you’ll be clean. Tomorrow when you get up start drinking water. A minimum of a GALLON a day is what I’d drink. Some days I’d polish off a gallon and a half. You want to drink it SLOW. Don’t pound it or guzzle the water as this will only have it run tight through you, and when you start peeing water will be coming out your ass too. Thus wasting all that time and water. Within about hour to ninety minutes you’ll start peeing a lot. This is good. This is what you want. Drugs like are metabolized out your body through the liver and the kidneys with the majority of it passing in urine. Continue drinking a gallon tomorrow. Then Wednesday and Thursday you can taper down to half gallon if you want. Then come Friday you’ll be clean for your test. Basically the more water you drink the more you’ll pee. Removing the from your system at a much quicker speed (no pun intended, seriously;)
