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?

Consider the following problem: a box with an open top is to be constructed from a square piece of cardboard, 3 ft wide, by cutting out a square from each of the four corners and bending up the sides. find the largest volume that such a box can have.
