7.44. Three hundred L/h of a 20 mole% C3Hg-80% n-C4H10 gas mixture at 0°C and 1.1 atm and 200 L/h of a 40 mole% C,Hg-60% n-C,H10 mixture at 25°C and 1.1 atm are mixed and heated to 227°C at constant pressure. Enthalpies of propane and n-butane are listed below. Assume ideal-gas behavior. Propane Ĥ(J/mol) Butane T(°C) H(J/mol) 25 1772 2394 227 20,685 27,442 (a) Calculate the heat requirement in kJ/h. (See Example 7.6-2.) (b) Where in your calculations did you use the ideal-gas assumption?
