The compression ratio of an air-standard Otto cycle is 9.5

The compression ratio of an air-standard Otto cycle is 9.5. Prior to the isentropic compression process, the air is at 100 kPa, 17 C, and 600 cm2. The temperature at the end of the isentropic expansion process is 800K. Using specific heat value at room temperature, determine: 1. The highest temperature and pressure in the cycle 2. The amount of heat transferred, in kJ 3. The thermal efficiency 4. The mean effective pressure Show the cycle on P-v diagram and state all assumptions and show units.

Refrigeration problem.

A large refrigeration plant is to be maintained at -15C, and it requires refrigeration at a rate of 100kW. The condenser of the plant is to be cooled by liquid water, which experiences a temperature rise of 8C as it flows over the coils of the condenser. Assuming the plant operates on the ideal vapor-compression cycle using refrigerant 134-a between the pressure limits of 120 and 700 kPa, determine 1. The mass flow rate of refrigerant 2. The power input to the compressor 3. The mass flow rate of the cooling water Show the cycle on T-s diagram and state ALL assumptions and proper units.
