10.37 Two (2) kmol.hr-1 of liquid n-octane (species 1) are continuously mixed with 4kmolhr1 of liquid iso-octane (species 2 ). The mixing process occurs at constant T and P; mechanical power requirements are negligible. (a) Use an energy balance to determine the rate of heat transfer. (b) Use an entropy balance to determine the rate of entropy generation (WK1 ). State and justify all assumptions
