Heat Exchanger V1 = 8.80 L/s acetone n2 mol/s acetone P2 = 1 atm Saturated acetone vapor enters a heat exchanger at a rate of 8.80 L/s at 1 atm, and emerges from the heat exchanger as a saturated liquid at the same pressure. Water at 1 atm enters the heat exchanger at 11.5°C and at a rate of 8.65 mol/s. Assume that the heat exchanger operates adiabatically with respect to its surroundings. Calculate the temperature of exiting water by...
