Steam flows steadily through a turbine. The steam enters the turbine at a pressure of 4.5 MPa and a temperature of 700 °C. The steam exits the turbine at a pressure of 0.5 MPa with a velocity of 170 m/s. The mass flow rate of the steam is 25 kg/s and the inlet velocity is negligible. The rate of heat loss is 440 kW and the power generated by the turbine is 22 MW. Calculate the temperature at the exit of the turbine (°C).

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.

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
