Head or pressure loss due to friction in oil pipes - various viscosity and laminar flow.
Head or pressure loss in oil pipes with laminar flow can be calculated with the table below:
|Head loss - h -||1.7 104 f / d4||11 104 f / d4||20 104 f / d4||110 104 f / d4||220 104 f / d4|
h = head loss (moil / mpipe ) - meter oil per metre oil pipe - length of pipe includes allowances for bends, valves and fittings
f = flow of oil (liter/s)
d = internal diameter of pipe (mm)
The Reynolds number can be calculated from the table below:
|Reynolds number||32 104 f / d||4.5 104 f / d||2.8 104 f / d||0.45 104 f / d||0.25 104 f / d|
