WebTable 14.7 Pressure Loss in Fittings and Valves Expressed as Equivalent Length of Tube; Table 14.7a Pressure Loss in HVACR Elbows Expressed as Equivalent Length of … WebThis table lists the valve and fitting and an associated length of straight pipe of the same diameter, which will incur the same pressure loss as that valve or fitting. For example, if a 2" 90 o elbow were to produce a pressure drop of 1 psi, the equivalent length would be a length of 2" straight pipe that would also give a pressure drop of 1 psi.
