Ok found the formula Δp = (v² × f × L × ρ)/2D
With the pressure drop how would I convert to volume drop or energy required to accomidate for that pressure drop?
(I tried ideal gas law but that definitely doesn't work)
I found Reynolds number and relative roughness then used the moody diagram to find the friction factor, but not sure how to get to pressure drop from there. Why is shear stress needed?
(Have velocity, distance, diameter, viscosity, flow rate also)
Disregard that last post...
I could convert the pressure drop to volume drop, and using the efficiency of the compressor find out how much energy it takes to generate that much volume correct?
Ok I think I've calculated everything...
Would converting this pressure drop to pounds per square foot then using that in
(pounds per square foot * cfpm)/33000 = theoretical horsepower allow me to quantify the energy needed to compensate for this drop?
Sorry if I'm not understanding correctly I'm pretty new to this stuff
I'm trying to determine total cost to run a compressor based of the energy required to push compressed air to the receiving device plus the cost of the compressed air being used at the receiver.
The actual of the compression...
Let's say a receiving device that requires compressed air is 1.5 miles away from the source and demands 600 cubic feet per minute. Let's say the pipes have a diameter of four inches and already contain air at 90psi.
If friction in the pipes would be ignored, it would require the same amount...
