A gas mixture containing 30 mol% C3H8 and 70% n-C4H10 at 0 ° C temperature and 1.1 atm pressure is mixed at a flow rate of 300 L / h. Another gas mixture containing 45 mol% C3H8 and 55% n-C4H10 at 25...

A gas mixture containing 30 mol% C3H8 and 70% n-C4H10 at 0 ° C temperature and 1.1 atm pressure is mixed at a flow rate of 300 L / h. Another gas mixture containing 45 mol% C3H8 and 55% n-C4H10 at 25 ° C temperature and 1.1 atm pressure is mixed at a constant pressure of 227 ° C with a flow rate of 132 L / h. Calculate the amount of heat required in kJ / h. C3H8 and n-C4H10 enthalpies are given below. Make an ideal gas acceptance.
