Question

answer 81-82

Open with Thermodynamic Keys First Law Questions 81-85 are based on the stated information below. The air temperature in a piston-cylinder at the beginning of an adiabatic compression process of an ideal air standard cycle with a compression ratio of 18 is 300-K, the pressure is 0.1 MPa. Heat addition occurs next during a constant pressure process that starts with the piston at top dead center of 1800-K. The next process in the cycle is an adiabatic expansion which h followed by a constant volume cooling process to complete the eycle.
