Hi I need help with parts of a thermo practice problem 2 kg of air in a piston cylinder initially at P1=101 kPa, T1= 300 K undergoes a cycle made up of three processes: 1-2 Isothermal compression until the volume is (1/15) of its original value.2-3 Constant Pressure heating3-1 Isentropic Expansion back to the initial state Assume air is an ideal gas with constant specific heats with the following values: Cpo=1.027kJ/kgK; Cvo= 0.740 kJ/kgK; R=0.287 kJ/kgK; ɣ=1.388 Fill in the processes table below and show all work.
Steam at 44 bar and a dryness fraction, x = 0.9 is throttled to a pressure of 12 bar. Calculate thedifference in power output in kilowatts between the following two expansion processes:a) Steam at the initial pressure of 44 bar and x = 0.9 at State 1 is expanded in a turbine to State 3 at 0.12 bar.b) Steam at the reduced pressure of 12 bar after throttling at State 2 is expanded in another turbine to State 4 at the same exhaust pressure of 0.12 bar.The mass flow rate of steam is 8 kg/sec in both cases and the expansion in both turbines can be assumed to be reversible and adiabatic. Sketch both expansion processes on the same T-s diagram using the respective initial and final state points as described above.Explain the reason for the difference in power output.Calculate the mass flow rate of steam for the turbine operating at the throttled/reduced pressure to generate the same output as the turbine operating at the pressure before throttling.NOTE: You are required to number the state…
