A protein solution is being ultrafiltered using in a rectangular membrane module, which totally retains the protein. The unit dimensions (length, width, height are: 50cm,20cm,5cm, respectively). The crossflow velocity is 4.4m/s. The protein solution bulk concentration is 4.4g/L, and the wall concentration is estimated as 10g/L. The protein diffusivity is 9.51011m2/s, and assuming the protein solution viscosity to be same as that of water, determine the permeate flux
