A rigid, well-insulated tank is initially empty. The tank is kept connected by means of a valve to a steam line carrying steam at 2 MPa and 400 °C. The valve is opened and the steam flows slowly into the tank until the tank pressure balances with the pressure of the line. Determine the final temperature of the steam in the tank. *Take note that the line pressure is kept constant during this process.
An insulated, vertical piston–cylinder device is purchased from a manufacturer. Upon purchase, it contains 3 kg of water at precisely 20 degrees celcius. The mass of the piston is such that it maintains a constant pressure of 300 kPa inside the cylinder. Liquid water at 2 MPA and 873.15 Kelvin is allowed to enter the cylinder from a supply line until the instant that the last drop of liquid in the cylinder vaporizes (saturated vapor). Find the mass of the steam that has entered [kg].
The power required to compress 0.01 kg/s of steam from a saturated vapor state at 50°C to a pressure of 800 kPa at 200°C is 6 kW. Find the rate of heat transfer from the compressor.

A piston system contains a hot fluid at 250kPa pressure that is cooled while being stirred by a paddle wheel. Initially, the internal energy of the fluid is 1500 kJ and volume is 2m3. During the cooling process, the fluid loses 400 kJ of heat, and the paddle wheel does 100 kJ of work on the fluid. At the end, volume reduces to 0.5m3. Pressure remains constant. Determine the final internal energy of the fluid. Neglect the energy stored in the paddle wheel.
A Piston-Cylinder system initially contains R-134a refrigerant at a temperature of 2.8 bar and 40°C and an initial volume of 0.1 m3. First, heat is transferred to the system by keeping the piston constant and this process is continued until the pressure is 3.2 bar. The process is then maintained by allowing the volume to change while the pressure is kept constant. At the end of this process, the temperature reaches 50°C. Assuming the state changes as if they are balanced,calculate;a) The mass of R-134a refrigerant in the system,b) The amount of heat transferred during the fixed volume process,c) The amount of heat transferred during constant pressure operation.d) Show the state changes on the P-v diagram.
