Provide the diagram, given, and step by step solution for below problem. An Otto cycle has an initial condition of 102 kPa and 32°C with compression ratio of 8.The maximum temperature of the cycle is 1400°C. Find the mean effective pressure in Kpa per kilogram of air.
In an ideal otto cycle, heat supplied is 920 Kj/kg and the highest temperature inthe cycle is 1600 deg. C. Calculate the following:a. Temperature at the end of the isentropic compression processb. Change in entropy of a process.
Consider a 10:1 pressure rise in the ideal compressor with air as the working fluid compared to the a pump with water as the working fluid and the same pressure rise and same inlet pressure. Check all that apply The compreesor takes 300 times more work/unit mass as the pump The work per unit mass is about the same between the two. Becase the pump deals iwth a liquid the work will be higher. The compressor in a Brayton cycle has a much greater effect on performance than a pump in a Rankine cycle.
