Problem 12.015 a mixture having a molar analysis of 66% n2, 17% co2, and 17% h2o enters a turbine at 1850°r, 8 atm, with a mass flow rate of 5 lb/s and expands isentropically to a pressure of 1 atm. the turbine operates at steady state and kinetic and potential energy effects can be ignored. (a) the temperature at the exit, in k. (b) the power developed by the turbine, in kw.

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
