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
∆
. 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.
Housing
p∆
: Pressure loss curve, housing
Differential pressure (bar)
Flow rate (l/min)
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.
