Loss of Pressure Through Screw Pipe Fittings Calculator

This chart defines the Loss of Pressure Through Screw Pipe Fitting. Each pipline fitting within the system (Gate Valve, Long Radius, pipe elbow, angle valve, close return bend, tee, globe vavle) should be accounted for separately in your system pressure loss calculations or model.

Given in equivalent lengths (feet) of straight pipe.
