Apiston-cylinder apparatus contains water at an initial temperature of 80°c and specific volume 3.1 m®/kg. heat is transferred to the water, while the pressure is held constant, until the temperature increases to 160°c. determine the heat transfer to the water, and the work done on the piston, per unit mass of water.

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
