An air-standard otto cycle has compression ratio 10 and maximum cycle temperature 1000 k. evaluate the thermal efficiency and specific work of the cycle. what would be the thermal efficiency and specific work if it was a diesel cycle to the same maximum temperature? what would be the thermal efficiency and specific work if it was a dual pressure cycle to the same maximum temperature, where half the energy addition was from constant volume and half the energy addition as from constant pressure?

What component of earth’s atmosphere exists entirely as a result of photosynthesis?
