The air flow that is stated in the compressor specs, is most of the time Nl/s (or S cfpm), which means вЂњNormal liters per secondвЂќ (or standard cubic feet per minute).

This is the maximum amount of air the compressor is able to pump out, at the rated pressure.Д«ut be careful, there is one important thing to look out forвЂ¦ l/s vs. There will always be one line that tells you the maximum output of the machine in liters/second, m3 per minute or hour, or cubic feet per minute (cfpm).

The easiest way to find out the (maximum) air flow, is too look at the specs of your compressor (look in the manual or search online). To start, you need to know the air flow through your system.

In short, the information we need to calculate pressure drop are:

ThatвЂ™s why you always need to measure the pressure drop at full air consumption (all machines/air tools running, worst case scenario). This also means, that when no air is used at all (at night, in the weekends), there is no pressure drop. The more air needs to pass through a pipe at once, the bigger the pressure drop. The amount of air passing through the pipe is also a factor. The pipes themselves of course, but also bends in the pipe, couplings, flexible hoses, quick-connect coupling, they all create pressure drops.ДЄnd, the longer the pipe, the bigger the pressure drop will be. In short, every obstruction creates a pressure drop. For example 6.9 bar at the point-of use and 7 bar at the compressor. Therefore, the pressure drop should be maximum 0,1! This means that the pressure at the point-of-use should be maximum 0.1 bar lower than the pressure at the compressor outlet. The higher the setpoint of your compressor, the more energy (and money) it will use. If the pressure drop becomes too high, you will need to set your compressor on a higher setpoint. Now, whatвЂ™s the problem with pressure drop you ask? The result is a pressure drop between the beginning of the pipe and the end of the pipe. If too much air needs to pass a too small pipe, it will have trouble passing through this pipe. WhatвЂ™s the problem with a too small compressed air pipe? ItвЂ™s either because the factory or workshop has grown over time, and the old system became too small (quite understandable), or they just installed a too small pipe to begin with!

I still see too many places where the pipe size of the compressed air system is too small. Need to work out the Pressure Drop of fluids moving through a tube or pipe?

If the set of conditions entered in the model generate negative answers, then clearly it is necessary to adjust the variables as appropriate until a realistic result is obtained. With this being the case, they will be accurate to within 10% of the actual results obtained. The graphs above are generated from calculations assuming the hose to be in good condition and laid in a straight line. If the head is given in metres of water, each 1-metre head (3.28 ft) induces 0.1 bar (1.47 psi.) pressure.ДЄll formulae for finding the amount of fluid that will flow through a hose at a given time, are approximate. The pressure is sometimes stated as вЂhead of waterвЂ™. The surface character of the bore, the number, and shape of bends incorporated in the run of the hose also influence the flow rate. The quantity of fluid that will be discharged through a hose depends on the pressure applied at the feed end, the hose length and bore diameter. Quantity Fluid Flow vs Bore Diameter Data
