Filter calculation
The total pressure of the filters at a specific flow rate is comprised of the housing
p
and the 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.
Pressure loss curve, housing
The upper housing curve applies for mineral oil with a density of 0.86kg/dm³ and a
kinematics viscosity of 30mm²/s. 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.
Differential pressure in bar
Flow rate in l/min
The housing curve applies for water at 20°C.
