An ideal otto cycle has a compression ratio of 9. at the beginning of the compression process p =100 kpa and t=27°c. the maximum cycle temperature is 1100°c. find the temperature, pressure and specific volume at states 1,2,3, and 4. find the heat supplied, heat rejected, work done by the system, work done on the system, net work done, and thermal efficiency. calculate the thermal efficiency of a carnot cycle operating between the same temperature limits.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
