**Standard cubic feet per meter (SCFM)** is one of several ways to formally describe the flow rate of gases. SCFM measures how much ofthe matter that makes up a gas(or mixture of gases) passes through a given region of space per unit time. This is in contrast to the simpler and mo...
Does the general location the fan or blower is operating in contain any type of explosive or flammable material or liquid? If the fan or blower will be used to convey material, answer the following: What is the material? How much does the material weigh, in pounds per cubic foot?
Larger pipes store more air; 500 feet of 1” pipe will store about 18 gallons of air, while 500 feet of 2” pipe will store about 77 gallons. This is not the most efficient way to store air; if air storage is your primary consideration, it is much more cost-effective and efficient ...
Peak horsepower is the maximum output that a motor can produce while the motor has the start windings engaged. Peak HP can be as much as 5-7 times the rated or running HP. Under normal operating conditions, the start windings are only engaged for a small fraction of a second. Therefore,...
PD meters are available in sizes from 1/4" to 12" and can operate with turndowns as high as 100:1, although ranges of 15:1 or lower are much more common. Slippage between the flow meter components is reduced and metering accuracy is therefore increased as the viscosity of the process ...
They never said much about leaks, yet I can still recall leaking air lines in my father's workshop. In the factory setting, a steam leak is obvious and an oil leak even more so, but air leaks don't create a visible plume, nor do they make a dangerous and slippery mess on the ...
One California operator speculates that the landfill he helps run will see negligible short-term impact; actually, he projects the operation is a good 20 years out from seeing much change in how it operates due to less organics. Another operator expects SB 1383 will have both short-...
Why was this leak not discovered much much sooner, when the leaky opening was pinhole sized?Watch out: this gas leak is a very serious safety concern, as any gas leak gives the potential for a building fire or explosion or asphyxiation of the occupants (injury or death). So the first ...
when the air gap is at its maximum, solenoid valves draw much higher currents than when the core is completely retracted, i.e., the air gap is closed. This results in a high output and increased pressure range. In DC systems, after switching on the current, flow increases relatively ...
