Constant pressure filtration - scale up

A pilot experiment used a filter of 0.1 m² area at a constant pressure of 68.5x10⁴ Pa. The filtrate viscosity was 0.0015 Pa s, slurry concentration was 3% w/w, cake concentration was 52% w/w and the liquid density was 1000 kg m^-3.

The constant pressure filtration equation is:

The dry cake mass per unit volume filtrate is 31.8 kg m^-3, the specific resistance is and the medium resistance is .
