Resistance coefficient K and equivalent length l/d calculation for valves and fittings

Calculator can be used for resistance coefficient (or resistance factor) K and equivalent length l/d calculation for valves and fittings. Resistance coefficient K and equivalent length l/d is proportional coefficient between pressure drop (head loss) and square velocity of fluid flowing through valves and fittings like elbow, bend, reducer, tee, pipe entrance and exit. Resistance coefficient and equivalent length l/d calculator should be used with pressure drop calculator to calculate pressure drop in piping system that includes obstructions like fittings and valves.

Based on the size and shape of valves and fittings different values for resistance coefficient and equivalent length l/d are calculated. You can use it for resistance coefficient K and equivalent length l/d calculation for elbows, pipe bends, mitre bends, return bends, standard tee, pipe entrance, pipe exit and for sudden and gradual enlargement or contraction of pipe.

Resistance coefficient K and equivalent length l/d calculator for valves and fittings requires Java^TM.
