question #1...please answer as detailed as possible

Question 1: - To determine the suitability of silicone rubber for its use as a membrane for a heart-lung machine to oxygenate blood, an experimental value of the permeability at 30C of oxygen was obtained, where PM = 6.50x10cm Oz (STP)/(s.cm.cmHg/mm). a) Predict the maximum flow of Oz in kgmol/s.m2 with an O2 pressure of 700mmHg on one side of the membrane and an equivalent pressure on the blood film side of 50mm. The membrane is 0.165mm thick. Since the gas film is pure oxygen, the gas film resistance is zero. Neglect the blood film resistance in this case. b) Assuming the maximum requirement for an adult of 300cm?O2 (STP) per minute, calculate the membrane surface area required in m2. (Note: The actual area needed should be considerably larger since the blood film resistance, which must be determined by experiment, can be appreciable.)
