The following data were obtained in a constant pressure filtration unit for filtration of a yeast suspension at Δp = 7.7 psi.

t (sec): 18.9, 45.1, 76.7, 112.3, 207.1

V (L filtrate): 0.55, 1.1, 1.6, 2.1, 3.05

The filter has the following characteristics:

A = 440 cm2, c = 23.5 g l-1, μ = 8.9 x 10-4 kg m-1s-1

a)Calculate the parameter  for the filter medium.

b)Determine the filter medium resistance, rm.

c)What additional data would you need to evaluate the compressibility coefficient (s)?
