Thank you for the info on the document i think it may be invaluable to me in the futrue, however right now i don't believe the DW equation is what I am looking for, unless there is a way of restating it that works for my case.
I'm trying to get the dp with the sudden change of diameter...
take it like 4 lanes of cars going down to 2 lanes and the cars are invencible and the cars continue to come at a steady rate, basically for the system to work the cars moving into the 2 lane section will have to move faster. that analogy handle the mass but not the pressure but you get the...
well i know when you decrease the pipe size and volumetric flow rate remains constant - velocity increases and pressure drops, i would assume the inverse is true with a distinct loss of energy but I'm unsure as to the driving equation as every "online calculator" throws a fit if you go small to...
Air flow in shop is through 1/4" hose. pneumatic motor has 1/2" inlet plus the tubeing to and from valve is also all 1/2" tube. what would be a general equation to model the pressure loss or increase to the motor.
Shop air:
80psi 60cfm
