A constant pressure piston/cylinder has 1 kg of saturated liquid water at 100 kPa. a rigid tank contains air at 1200k, 1000 kPa. they are now thermally connected by a reversible heat engine cooling air tank and boiling the water to saturated vapor. Find the required amount of air and the work out of the heat engine.

Figure 1 presents a seawater cooled steam ejector refrigeration/Heat Pump System for Naval Surface Ship Applications. A Steam Ejector Refrigeration System is thermally driven heating and cooling technology by changing the pressure to control the boiling temperature which will enhance evaporation of fluid to realize cooling purpose. A heat pump system is to utilize the phase change of fluids to realize heating and cooling purpose. Please answer following questions: exhaust gas boiler nozzle section...

QUESTIONS 1. Refrigerant-134a is cooled by water in a condenser. The refrigerant enters the condenser at a pressure of 1 MPa and a temperature of 70°C at a flow rate of 6 kg / min and exits at a temperature of 35 °C. Cooling water enters the condenser at 300 kPa pressure and 15 °C temperature and exits at 25 °C temperature. By neglecting pressure losses, Calculate; a) mass flow of cooling water b) the heat transfer from the refrigerant...

1.Water vapor contained in a piston–cylinder assembly undergoes an isothermal expansion at 277°C from a pressure of 5.1 bar to a pressure of 2.7 bar. Evaluate the work, in kJ/kg. 2.Nitrogen (N2) contained in a piston–cylinder arrangement, initially at 9.3 bar and 437 K, undergoes an expansion to a final temperature of 300 K, during which the pressure–volume relationship is pV1.1 = constant. Assuming the ideal gas model for the N2, determine the heat transfer in kJ/kg. 3.Argon contained in...

Can you please help me with these 5 problems!!! please and thank you Question 1 A mass of 5 kilograms of carbon dioxide (CO2) in a piston-cylinder assembly undergoes two processes in series from an initial state where p1 = 2.4 MPa, T1 = 260°C: Process 1–2: Constant-temperature expansion until the volume is twice the initial volume. Process 2–3: Constant-volume heating until the pressure is again 2.4 MPa. Assuming ideal gas behavior, determine the overall work, in kJ. ____________________________________________________________ Nitrogen...
