6-In an ideal diesel cycle the pressure and the temperature at the beginning of compression are 98.5 kPa and 60°C, respectively. The maximum pressure attend during the cycle is 4.5MPA and heat received during the cycle is 580KJ/kg. Determine a-the compression ratio b- the temperature at the end of compression b- the temperature at the end of combustion 1.0021 UL

An ideal diesel cycle powered by air has a compression ratio of 20. At the beginning of the compression process, the pressure of the air is 100 kPa, the temperature is 20°C, and it is desired that the highest temperature of the cycle should not exceed 2250 K. Show the cycle in the P-v diagram. Assume the specific heats are constant at room temperature.  k=1.4 CP=1.005kJ/kgK CV=0.718 kJ/kgK R=0.287kJ/kgK a) Calculate the heat entering and leaving the cycle, the thermal efficiency of the cycle, b) Calculate the average effective pressure of the cycle.

first 2 parts please

The pressure and temperature at the beginning of compression of a cold air-standard Diesel cycle are 90 kPa and 300 K, respectively. At the end of the heat addition, the pressure is 7.2 MPa and the temperature is 2250 K. Assume constant specific heats evaluated at 300 K. Determine the mean effective pressure, in kPa.
