Calculate the filtration flow rate Q (cm3/sec) of a pure fluid across a 100 cm2 membrane. Assume the viscosity (u) of the fluid is 1.8 CP. The porosity of the membrane is 40% and the thickness of the membrane is 500 pm. The pores run through the membrane at an angle of 30, and each has a radius of 0.225 um. The pressure drop applied across the membrane is 75 psi
