Three hundred Llh of a 20 mole% C3Hg-80% n-C4HIO gas
Chapter 7, Problem 7.40(choose chapter or problem)
Three hundred Llh of a 20 mole% C3Hg-80% n-C4HIO gas mixture at OC and 1.1 atm and 200 Llh of a 40 mole% C3Hg-60% n-C4H lO mixture at 25C and 1.1 atm are mixed and heated to 227C at constant pressure. Calculate the heat requirement in kJ/h. (See Example 7.6-2.) Enthalpies of propane and n-butane are listed below. Assume ideal gas behavior. Propane Butane T(C) HU/mol) HUlmol) 0 0 0 25 1772 2394 227 20.6~5 27,44
