Saturated acetone vapor enters a heat exchanger always a rate of v1=1.30L/s at p1=1 atm and emerges from the heat exchanger as a saturated liquid at the same pressure. H2O at p3= 1atm enters the heat exchanger at t3=14.5°c and a rate of n3=5.04mol/a. Assume that the heat exchanger operates adiabatically with respect to the surroundings. Calculate the temperature of exiting water, T4, by following these steps. At what temperature does acetone enter the heat exchanger ? What is the heat of vaporization of acetone at this temperature ? Use the ideal gas law to calculate the moles of acetone entering the heat exchanger. Assume that the heat capacity of water for the temperature range in the heat exchanger is constant at cp=7.54x10-5 kj/mol*°c. What is the temperature of water leaving the heat exchanger ?
