Steam to a turbine at a mass flow rate of 1.4 kg/s, 700 kPa pressure and 400 °C enters the temperature. Steam at 100 kPa pressure and 1.4 m3/kg specific volume exits the turbine. Heat transfer from turbine to environment 50 kW, with turbine Since the boundary temperature between the environment is 70 °C, a) Find the power produced by the turbine, entropy produced in the turbine and isentropic efficiency of the turbine. Note: The changes in kinetic and potential energies will be neglected and T (K) = 273 + °C will be taken.

R-134a is throttled in a line flowing at 25°C, 750 kPa with negligible kinetic energy to a pressure of 165 kPa. Find the exit temperature and the ratio of exit pipe diameter to that of the inlet pipe (Dex/D;n) so the velocity stays constant.

Air is compressed from 120 kPa and 350 K to 1200 kPa and 750 K. a) Calculate the change in specific entropy As of the air using constant specific heat capacities at 550 K and equations based on cp, Cv, and the heat capacity ratio k. b) Calculate the change in specific entropy As of the air using equations and table values (A-17), which account for the changes in heat capacities with temperature. c) What will the temperature at the end of the compression process T2, be, if the pressure after compression is 1200 kPa, the compression process is isentropic, and you use constant specific heat capacities at 550 K and equations based on Cp, Cv, and the heat capacity ratio k. d) What will the temperature at the end of the compression process T2, be, if the pressure after compression is 1200 kPa, the compression process is isentropic, and you account for changes in heat capacities with temperature by using corresponding equations and table values? e) Calculate the deviation between the results…

Thermodynamics sketch and label the turbine. Sketch and label the process on a T-s diagram also mentions all numbers on the process please. Thanks 7.56 A steam turbine has an inlet of 2 kg/s water at 1000 kPa, 400°C with velocity of 15 m/s. The exit is at 100 kPa, 150°C and very low velocity. Find the power produced and the rate of entropy generation.
