mass is 75kg
A diatomic gas is initially at 280 K when its volume is equal to your volume and its pressure is 100,000 Pa. It is compressed isothermally to a volume of 1.00x103 m2 and then allowed to expand isobarically for a while before expanding adiabatically back to its original state. What is your volume? What are the pressure, volume, and temperature at the end of the isothermal process? 3. 4. (Hint: your density is approximately 1 000 kg/m2.)...

Problem 4 Consider a gas power cycle executed in a closed system with 0.08 kg of gas. The gas is initially at 120 kPa, 2°C. First,910 kJ/kg of heat is added under constant volume. Then, more heat is added under constant pressure such that the gas reaches 1387°C. Then, the gas is expanded isentropically to 120 kPa. Finally, heat is rejected from the system under constant pressure such that it returns the gas to its initial state. Assuming air-standard cycle...
