Arigid thermally conductive container containing liquid refrigerant 11 has a leak. the conditions outside the tank are 298 k and 100kpa. the starting mass of r-11 is 7kg, at the end of the process only 3kg remain(as a two phase mixture). temperature remains constant throughout the process. at this point it is a two phase mixture. determine the final quality of the two phase ,mixture.

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
