engineering thermodynamics for electrical engineers
1. A piston enclosed 2kg of saturated water with a quality of 10% initially. The piston pressure is 1 MPa. The water is heated in the system as shown in the figure until the final state of the water is saturated vapor. When the piston rests on the stop the additional volume enclosed is 0.19m3. Determine the work done by the water and the final temperature and pressure. Neglect the volume occupied by the piston.

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...

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?

1. A saturated water liquid-vapor mixture with a total mass of 1.3 kg is contained in a piston-cylinder assembly, with the piston initially placed so that the volume of the mix- ture is 1.5 m. The initial temperature of the mixture is 30°C. The piston is then pushed inward until the volume is halved, and the container is heated until the pressure is 400 kPa. Determine Sherleader 306 V Tup V 400 kPa (a) the quality of the mixture for...

Reffering to this picture, water contained in a piston-cylinder assmbly, initially at 1.5 bar and a quality of 20%, is heated at constant pressure until the pistonhits the stops. Heating then continues until the water is saturated vapor. Show the process of the water in series on a sketch of the T-v diagram. For the overallprocess of the water, evaluate the work and heat transfer, each in KJ/kg. Kinetic and potential effects are negligible.please.... :)
