16. Two pounds of air at 100 psia occupy 4 cu ft; the air is heated and expands at a constant pressure until its volume is increased 300. per cent; after that the air expands adiabatically to 50 psi, and finally its pressure is 1educed isochorically to 15 psi. Determine the changes of available and unavailable energy and of the entropy between the starting and final condi- tions. Assume the refrigerator temperature to be 70 F, and use everage specific heats for the temperature range involved.

Steam enters the nozzle operating a steady state pressure of 2.5 MPa and a temperature of 300 °C ( H1 = 3008.8 kJ/kg) and leaves at a pressure of 1.7 MPa with a velocity of 470 m/s. The rate of flow of steam through the nozzle is 1360 kg/hr. Neglecting the inlet velocity of the steam and considering the flow in the nozzle is adiabatic, find:a. the exit enthalpy in kJ/kg, ( H2)b. the nozzle exit area ( in cm) if V exit is 0.132 m^3 /kg c. the system
A single-stage double-acting air compressor compresses the air from 1 bar to 5 bar. The compressor runs at 2.2 rps and work done during the compression is 36 kJ. Calculate the power required in kW. the power required in kW
A two stage compressor is used to compress 800 m3 /h of CO2 measured at 288K and 1 bar from its initial state of 0.5bar and 30k to a pressure of 1.5 bar with inter cooling to 300K. A compression efficiency of 85% may be assumed in each stage. Calculate the power required to run the compressor and the discharge temperature.
