Calculating the pressure loss of the filter housing / filter element

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

Housing
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 may not exceed 3 m/s at the filter
inlet for oil and 4 m/s for water.
