Water is contained in a piston-cylinder device, where the piston can move in order to maintain a constant pressure of 300 kPa. Initially, the temperature of the water is 200 degrees Celcius. Heat is removed from the water until it reaches a quality of 0.1. Find the amount of heat transfer to achieve this, in kJ/kg. Answer value in kj/kg

Five kg of water is contained in a piston–cylinder assembly, initially at 5 bar and 200°C. The water is slowly heated at constant pressure to a final state. The heat transfer for the process is 3260 kJ and kinetic and potential energy effects are negligible. Determine the final volume, in m3, and the work for the process, in kJ.

Referring to the figure shown below, water contained in a piston–cylinder assembly, initially at 1.5 bar and a quality of 60%, is heated at constant pressure until the piston hits the stops. Heating then continues until the water is saturated vapor. The initial height, L1, is 0.05 m and the change in height, L2, is 0.03 m. For the overall process of the water, evaluate the work and heat transfer, each in kJ/kg. Kinetic and potential effects are negligible.

A mass of 5.5 kg of saturated liquid-vapor mixture of water is contained in a piston-cylinder at 101.325 kPa. Initially, 2.3 kg of the water is in the liquid phase and the rest is in the vapor phase. Heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 300 kPa. Heat transfer continues until the total volume increases by 21 percent. Determine: a) the initial...

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...

Need Help with Thermodynamics Water vapor contained in a piston–cylinder assembly undergoes an isothermal expansion at 239°C from a pressure of 5.6 bar to a pressure of 3.4 bar. Evaluate the work, in kJ/kg. ------------------------------------------------------------------------------------------------------------------------------------------------------------------- Water, initially saturated vapor at 10.7 bar, fills a closed, rigid container. The water is heated until its temperature is 200°C. For the water, determine the heat transfer, in kJ/kg. Kinetic and potential energy effects can be ignored.
