Pressure loss through hose, tube or pipe
This tool gives a guide only. Final pressure drop should always be checked against hose, tube or pipe manufacturer data where available.
Default oil viscosity is 46 cSt. Cold oil can have much higher viscosity and cause significantly more pressure drop.

Important Note
This is a simplified pressure drop estimator. Actual pressure loss can change due to hose, tube or pipe construction, fittings, bends, adaptors, couplings, oil temperature, contamination, pulsation and manufacturer-specific pressure drop data.
