4.heat transfer

Carbon dioxide and nitrogen undergo equimolar counterdiffusion in a circular pipe (length: 1m, diameter: 50mm ). The system is at a total pressure of 1 bar and a temperature of 25C. The two ends of the pipe are connected to large chambers, such that species concentrations within the large chambers are constant. The partial pressure of carbon dioxide at one end is 0.132 bar, while at the other end it is 0.066 bar. What is the mass transfer rate of carbon dioxide through the pipe (in g/s )? What is the mass transfer rate of nitrogen through the same pipe (in g/s )? DAB for carbon dioxide and nitrogen is 0.160104m2/s at 293K. (25 marks)
