At steady state, a well-insulated compressor takes in air at 100f ,14.2 lbf/in^2, with a volumetric now rate of 1200 /min, and compresses it to 500°f, 120 lbf/in^2.kinetic and potential energy changes from inlet to exit can be neglected. determine (a) the compressor power, in hp, and (b) the volumetric flow rate at the exit, in ft^3/min.

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
