Q3→ Steam enters a steam turbine at a pressure of 4 MPa and a flow rate of 25 kg / s at 450 ° C. At a pressure of 1 MPa and a temperature of350 ° C, intermediate steam is drawn from the turbine at a flow rate of 5 kg /h. The remainder of the steam leaves the turbine at 10 kPa pressure and 0.90 dryness. 200 kW of heat loss occurs from the turbine to the environment. Ambient temperature is 25 ° C and pressure is 100 КРа. www a) Calculate the exergy (available work potentials) of the state points. b) Find the reversible amount of work and the actual amount of work during this process. c) Calculate the amount of irreversibility (exergy destruction) in this process. d) Calculate the second-law yield for this process.

! Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Five kilograms of air at 427°C and 600 kPa are contained in a piston-cylinder device. The air expands adiabatically until the pressure is 100 kPa and produces 450 kJ of work output. Assume air has constant specific heats evaluated at 300 K. Determine the entropy change of the air in kJ/kg-K. Use the table containing the ideal gas specific heats of various common gases. (You must provide an answer before moving on to the next part.) The entropy change of the air is kJ/kg-K.

Please explain nicely. Thanks.

Steam enters an adiabatic turbine at a given 9,200 kpa and the temperature is 475 degree celsius with a mass flow rate of 87 kg/s. The surrounding temperature is 300 kelvin. The effeiciency of the turbin is also said to be 0.75. With this given data, what would be the entropy generation rate, value of ideal work, and value of the lost work?   note: steam is superheated.
