pressure drop of pump return line ammonia
Hey,
I am searching for a formula to calculate the pressure drop of the pump return line (wet gas recírc. 2-5) of ammonia.
In practice the pump return line will be mostly one diameter bigger than the gas line but I need to calculate the pressure drop. Because the pipelength are more then 100 m (328 ft) and there is a suction mainvalve. To prevent high pressure drop over 2 K a calculation have to be.
Could you help?
Thanks
