The concentration of glutamine in blood is being reduced using a hollow fiber dialyser membrane with a counter-current flow arrangement. The concentration of glutamine in the inlet stream is 1 g/L while the blood flow rate and the dialysate (water) flow rate are 0.8 L/min and 0.9 L/min, respectively. The surface area of the membrane is 500 cm2 and the membrane mass transfer coefficient is 2.86 x 10^-2 cm/s. The blood side mass transfer coefficient is 8.77 x 10^-2 cm/s while the dialysate side mass transfer coefficient is 3.44 x 10^-2 cm/s. Find the residual concentration of glutamine in the blood if we assume that there is no flow of liquid across the membrane.
