Fluids: calculate pressure loss due to turns in pipe flow

17/11/2011· I am trying to estimate the flow rate in a long pipe of rectangular cross section. The pipe is 100 m long and has twenty 180 degree turns. I have been able to calculate the pressure drip for a 100m straight pipe, but I have not been able to estimate the losses due to the turns. Is there a way to

Compressed air pipe sizing calculation | the Workshop

The pipes themselves of course, but also bends in the pipe, couplings, flexible hoses, quick-connect coupling, they all create pressure drops. And, the longer the pipe, the bigger the pressure drop will be. The amount of air passing through the pipe is also a factor. The more air needs to pass through a pipe at once, the bigger the pressure drop.
