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.

Ten kilograms of water in a piston/cylinder arrangement exists as saturated liquid/vapor at 100 kPa, with a quality 20%. The system is now heated so that the volume triples. The mass of the piston is such that a cylinder of 300 kPa will float it. (a) Find the final temperature. (b) Find the heat transfer in the process. (c) What is the phase of water when the piston just starts to lift up? (d) Sketch the process on a P-v...

2) A) Water, initially saturated vapor at 10.8 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. B) A piston-cylinder assembly contains 2 kg of water at 210.6oC and 3 bar. The water is compressed to a saturated vapor state where the pressure is 50.7 bar. During compression, there is a heat transfer of energy from the...

Problem 6.016 Two pounds mass of water in a piston-cylinder assembly, initially a saturated liquid at 35 Ib/in, undergoes a constant pressure, internally reversible expansion to x 90%. For this reversible process, determine the work by integrating p dV and the heat transfer by integrating T dS, each Btu.

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...

A cylinder/piston arrangement contains saturated water at 115°C with a volume of 0.1 L (state 1). The system is heated, causing the piston to rise and encounter a linear spring, as shown in figure. At this point (state 2) the volume is 15 L, the piston diameter is 230 mm, and the spring constant is 115 N/mm. The heating continues, so the piston compresses the spring until all the water becomes saturated vapor (state 3). Neglect the weight of the...

1 A piston-cylinder device initially contain 0.4 m3 of 1.8- kg saturated liquid water and steam mixture at 110 kPa. A electric heater in the device is turned on and passes a current of 1.7 A from a 120-V source. Only transfer of electrical work and boundary work exist. The piston initially rests on a set of stops, and a pressure of 200 kPa is required to move the piston. Afterwards the system continues to raise the piston and eventually...
