Propane gas enters a continuous adiabatic heat exchanger at 50C and 1 atm and exits at 250C. Superheated steam at 300C and 5.0 bar enters the exchanger and exits as a saturated liquid at the same pressure. a) Taking as a basis 100mol/s of propane fed to the exchanger, draw and label a process flowchart. Include in your labeling the volume of propane fed (m3), the mass of steam fed (kg), and the volume of steam fed (m3). (2+2=4marks) b) Calculate values of the labeled specific enthalpies for this process. (5 marks) c) Use an energy balance to calculate the required mass feed rate of the steam. Then calculate the volumetric feed ratio of the two streams (m3 steam fed/ m3 propane fed). Assume ideal-gas behavior for the propane but not the steam and recall that the exchanger is adiabatic. (5+5=10marks) d) Calculate the heat transferred from the water to the propane (kJ/s)
