0 Saturated acetone vapor enters a heat exchanger at a rate of V = 8.20 L/s at P = 1 atm and emerges from the heat exchanger as a saturated liquid at the same pressure. Water at P3 = 1 atm enters the heat exchanger at T3 = 19.5 C and at a rate of n3 = 7.79 mol/s. Assume that the heat exchanger operates adiabatically with respect to its surroundings. Calculate the temperature of exiting water, T4, by following these steps. T = L/s acetone n, mol/s acetone P = 1 atm T n = nmol/s water P = 1 atm T At what temperature does acetone enter the heat exchanger? heat of vaporization: n = Heat exchanger n = n, mol/s acetone P = 1 atm What is the heat of vaporization of acetone at this temperature? T4= n, mol/s water P = 1 atm Use the ideal gas to calc 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 = 7.54 x 10- kJ/(molC). What is the temperature of water leaving the heat exchanger? C kJ/mol mol/s C 0 Saturated acetone vapor enters a heat exchanger at a rate of V = 8.20 L/s at P = 1 atm and emerges from the heat exchanger as a saturated liquid at the same pressure.
