A frictionless, freely moving piston-cylinder assembly with a mass of 85 kg and a cross-sectional area of 0.05 m2 is located at an atmospheric pressure of 97 kPa. The initial volume of the piston is 8.9 liters and contains 0.008 kg of air. Then, the volume is halved with the heat transfer from the piston-cylinder assembly to the environment. According to this; a) Calculate the final pressure of the container (kPa) in (bar), and its temperature in (K),b) Boundary work (kj),c) Calculate the amount of heat transfer to the environment (kj).R= 0.287 kj/kg K, g=9.81 m/s 2 (You can use other data from Thermodynamic Tables, Table 17 for air.)
It is a hot day in Atlanta and you and your friends bought an ice cream maker. The unit consists of a bowl and a base that rotates the bowl around a stationary mixing paddle. The walls of the bowl contain an unknown mixture that absorbs heat from the ice cream. The bowl must be frozen (-20°C) before use. Unfortunately, your friends have lost the instructions and can't remember how long to operate the unit. You tell them not to worry since you have mastered energy conservation problems and can calculate the amount of time required to freeze the ice cream. Looking at the box, you find the specifications for the unit: a) Inner surface area of freezing bowl: 600 cm2; b) Heat transfer coefficient for bowl:h = 0.025 J / (cm2 s .°C); c) Power required to stir the bowl (100% efficiency):25 W; d) Amount of ice cream mixture added: 1 kg; e) The rate of heat transfer is between the bowl and the milk. You know that solutes lower the freezing point of water. Assume that the freezing point is…

1- Suppose you are operating a steam turbine where the steam leaving the turbine is at 5 bar. This steam contains 95 wt% vapors. If the shaft work produced by the turbine is 1100 kJ/kg and the high pressure, high temperature steam enters the turbine at 100 bar (abs), what is the temperature of the steam entering the turbine? If water at 10°C is supplied to the steam boiler to generate steam, how much heat is required per kilogram of steam produced? You may assume that heat losses from the turbine are negligible.
In a piston-cylinder assembly, there is initially 2 kg of water at a temperature of 25 °C and a pressure of 100 kPa. Then heat is given to the water until its volume is 0.4 m3. At this point, the piston in the cylinder is fixed with a stopper, but the water in the cylinder continues to heat until its temperature reaches 300 oC. According to this, calculate a) the final pressure of the water, b) the amount of heat given to the water, c) the work done by the piston. d) Show these processes in the T-v (Temperature-Specific Volume) diagram
