A fuel-air mixture with a fuel-to-air equivalence ratio of 0.6 enters an engine cylinder at 400 K where it is then compressed. After compression the mixture is at 750 K. Calculate the power needed for this compression process if the air mass flow rate is 100 kg/hr. Also calculate the compression ratio for this process. Textbook : John B.
