What is a sprinkler's "K-factor The K-factor is the nozzles's / sprinkler's constant at a given volume flow rate and is generally calculated with a formula: K = Q / √ p K = sprinkler's / nozzle's constant
Q = volume flow rate (l/min)
p = pressure at the sprinkler / nozzle (bar) examples: K-factor 57 = 171 l/min / √ 10 bar
K-factor 80 = 240 l/min / √ 9 bar
K-factor 115 = 345 l/min / √ 9 bar Generally the thread (DN) is associated with a K-factor. 3/8″ DN 10 K-factor 57
½″ DN 15 K-factor 80
½″ DN 15 K-factor 115
¾″ DN 20 K-factor 160 == ==

What is induim used for?
Indium is used in coating high-performance engine bearings and is an ingredient in low melting point alloys for sprinkler heads, fire-door links, and fusible plugs.
What types of liquid in sprinkler?
Sprinkler systems used in buildings to put out fires quickly use water.
Does the size of the hole in a spinning sprinkler in a can effect how fast the sprinkler will spin?
Yes, because the bigger the size, the more water comes out causing it to move faster.
What unit of measure will you use in sprinkler container?
The unit of measure commonly used in sprinkler containers is gallons.
What is the voltage to a sprinkler valve from the control panel?
Most common North American garden sprinkler systems use 24 volts AC. The control units usually plug into a common 120 volt AC receptacle. Inside the control unit there is a transformer that reduces the voltage from 120 volts to 24 volts AC. If you look on the side of the sprinkler valve coil you will see the voltage and the amperage draw of the coil. It is the amperage draw of the coils that determines the number of sprinkler that should be on one sprinkler branch from the main water manifold. The total amperage of the circuit determines what the size of the wire should be to control the sprinkler coils.

How many gpm does a commercial fire sprinkler put out?
There are many variables. The sprinkler heads come in different sizes. Rate of flow will be determined by the head-size, the frictional losses in the supply pipework, and the head of water available. In a single building example, sprinkler heads of exactly the same type, and fed by exactly the same bore pipework, on three different floors will give three different flow rates. Simple answer? "It varies"
What is kfactor?
number of pulses per unit volume
Fire sprinkler heads gallons per minute?
100
Is it easy to relocate sprinklers to different areas of my lawn?
If you utilize an in-ground sprinkler system, relocating sprinklers will require you to tear up most of your lawn as you will need to reroute pipes and sprinkler heads. For above ground sprinkler systems, relocating sprinkler heads is fairly easy and is completely dependent on the length of your hose.

What type of sprinkler head is typically found in open warehouses with high ceilings?
Upright heads
Are there any sprinkler heads available that are designed to help with water conservation?
Yes, there are sprinkler heads available that will help with water conservation. MP Rotator, made by Hunter, is just one of the brands. You can read more about them by visiting http://www.hunterindustries.com/products/mprotator/.
How do fire sprinkler systems put out fires?
Fire sprinklers have two major components that operate in response to a fire: the fire sprinkler heads which are connected via a series of pipes to a fire pumps. Water pressure is kept in the head by a series of valves in the pump. and is kept in the heads by little vials of colored liquid. During a fire, the liquid inside the sprinkler heads heats up and starts to expand, eventually causing the vial to burst. Water that was kept in the pipes pours out of the sprinkler heads. The water pouring out of the sprinkler heads causes the pressure in the fire pump to drop. In response, the pump kicks on and pumps more water from the municipal water supply to keep the sprinkler flowing. NOTE: this is how "wet pipe" fire sprinklers, the most common types of fire sprinklers, work. Other sprinklers (dry pipe, deluge and pre-action) are slightly different.
Automatic fire sprinkler system?
An automatic sprinkler system is a system in which sprinkler heads are fixed in piping system were pipe is fully filled with water or air under pressure and, at a certain calibrated temperature, sensing elements in sprinkler head breaks and allows water flow. Other types of systems rely upon electrical sensors (smoke and heat sensors, or manual switches) to initiate the flow or to pressurize the pipe so that sprinkler heads activated by the heat will flow water. Somewhat more rare systems, for extremely high hazards such as rubber tire storage in a warehouse, may have sprinkler heads that are always "open", allowing the entire room to be flooded when the pipe is pressurized.
Does it make sense to use two inch pipe in a home sprinkler system when water enters through a one inch meter?
You will not have any pressure after the first few sprinkler heads.
What kind of paint is used on fire sprinkler pipe?
you can use what ever kind of paint you want to
