Problem 6.024 SI Two kilograms of water contained in a piston-cylinder sembly, initially saturated vapor at 340 kPa, is condensed at constant pressure to saturated liquid. Consider an enlarged system consisting of the water and enough of the nearby surroundings that heat transfer occurs only at the ambient temperature of 25°C. Assume the state of the nearby surroundings does not change during the process, and ignore kinetic and potential energy effects For the enlarged system, determine the heat transfer, in...

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...

A water-vapor mixture with a mass of 0.5 kg of at a quality of 50% is initially contained in a piston-cylinder assembly. The piston is unrestrained and it is weighted such that it maintains a constant pressure of 500 kPa inside the cylinder. Heat is transferred to the cylinder from a thermal energy source until the steam reaches saturated vapor conditions. Determine: (a) the total heat transfer, (b) the total amount of entropy production for the entire process, (c) Indicate...

A piston–cylinder device initially contains 0.6 m3 of saturated water vapor at 250 kPa. At this state, the piston is resting on a set of stops, and the mass of the piston is such that a pressure of 300 kPa is required to move it. Heat is now slowly transferred to the steam until the volume becomes 1.5 m3. Use the data from the steam tables. a) Determine the final temperature. b) Determine the work done during this process. c)...

A mass of 5 kg of saturated liquid-vapor mixture of water is contained in a piston- cylinder device at 125 kPa. Initially. 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 10%. We denote the...

2 kg Water in a vertical piston cylinder arrangement, is initially at saturated liquid state at 3 bar. It is heated and undergoes constant pressure expansion to a state of saturated vapor. What is the work done by the piston cylinder arrangement to the environment? Neglect the mass of the piston, piston friction, kinetic and potential energy changes. Hint: this is a closed system problem, remember control volume boundary work concept. What is the heat transfer into the water?

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...
