Two tanks are connected by a valve. the first tank initially contains 0.04 m3 of r-134a saturated liquid at 1.0 mpa. the other side is completely evacuated (mass and pressure are zero). the valve is opened and the refrigerant fills both tanks. the final state is 60 kpa and 0°c. determine the volume of the second tank.

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
