Saturated acetone vapor enters a heat exchanger at a rate of Vi = 1.30 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 = 11.0 C and at a rate of inz = 8.64 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. Heat exchanger V, L/s acetone 1 mol/s acetone P = 1 atm T n = n, mol/s acetone P = 1 atm T, n = r, mol/s water P = 1 atm T. n, mol/s water P, = 1 atm T, At what temperature does acetone enter the heat exchanger? T = C What is the heat of vaporization of acetone at this temperature? heat of vaporization: kJ/mol Use the ideal gas law to calculate the moles of acetone entering the heat exchanger. n = mol/s Assume that the heat capacity of water for the temperature range in the heat exchanger is constant at C = 7.54 x 10-2 kJ/mol.C). What is the temperature of water leaving the heat exchanger? T. = C
