Calculate the flux and the rate of removal of urea at steady-state in g/h from blood in a cellophane membrane dialyzer at 37oc. membrane thickness is 0.025 mm thick and has an area of 2m2. the mass transfer coefficient on the blood side is estimated as kc1=1.25x10-5 m/s and on the aqueous side is 3.33x10-5m/s. the permeance of the membrane is 8.73x10-6 m/s. the concentration of urea in blood is 0.02 g urea/100ml and in the dialyzing fluid urea concentration is assumed to be 0.
