Calculating the pressure differential of the filter housing / filter element
Calculating the pressure differential of the filter housing / filter
element
The total pressure of the filters at a specific flow rate is comprised of the housing
and the filter element
. The pressure loss of the housing can be determined
using the following pressure loss curve. The pressure loss of the filter elements is
computed on the basis of the R factors.

The upper housing curve holds for mineral oil with a density of 0.86 kg/dm³ and a
kinematics viscosity of 30 mm²/s. The lower housing curve holds for water at 20°C.
For turbulent flow, the differential pressure will change proportionally to the density;
for laminar flow, it will change proportionally to the density and viscosity. The flow
velocity should not exceed 3 m/s at the filter inlet for oil and 4 m/s for water.
