A 0.15 kg of air contained in a piston-cylinder device where the initial pressure was 2000 kPa and the temperature was 350°C. The substance has undergone several expansion and compression processes. The air is first expanded at a constant temperature to a pressure of 500 kPa and then compressed polytropically with a polytropic exponent of 1.2 to the initial pressure, and finally compressed isobarically to the initial state. Determine the boundary work for each process and the net work of the cycle.

A piston-cylinder arrangement contains water at 110°C, 85% quality with a volume of 1 L. What is the initial mass, in grams? The system is heated, causing the 150-mm-diameter piston to rise and encounter a linear spring with k = 800 kN/m. Calculate the specific internal energy (kJ/kg) at this instant knowing that the measured volume is 1.65 L. The heating continues and compresses the spring in the process. When the piston encounters the stops, the pressure is 200 kPa. What is the temperature (in °C) and entropy (in J/K) at this point? Heating continues until the pressure reached 300 kPa. What is the volume, in L at this instant? Illustrate the process in separate P-v and T-v diagram. Note:1000 L = 1m3. Hint: Draw the FBD of the piston in each state.
Shown in the figure, an insulated rigid tank is divided into two equal parts by a partition. Initially, one part contains an indeal gas, and the other part is evacuated. The partition is then removed, and the gas expands into the entire tank. At the initial state, the mass of the gas is m= 4.00kg, initial pressure is p1 = 600.00 kPa, initial temperature is T1 = 300.00 K. The gas constant is R = 0.2870 kJ/(kg·K). (The internal energy can be determined by the equation ΔU=m·cv·(T2-T1), where cv = 0.7180 kJ/(kg·K) is the specific heat at the constant volume.)

A rigid tank of volume 0.018 m is connected through a closed valve to a vertical cylinder fitted with a freely moveable frictionless heavy piston of area 0.02 m?. Initially, the rigid tank is filled with air at 500 kPa and 25 °C while the cylinder has air of volume 0.015 m³ at 25 °C. In the vicinity, the ambient air pressure is 100 kPa and the gravitational acceleration is 9.81 m/s. It is given that the 2 air can be assumed to behave as an ideal gas with the gas constant R = 0.287 kJ/kg.K. (a) At this initial state, determine the air pressure in the cylinder. The valve is then slowly opened and left opened, allowing the pressurised air from the rigid tank to flow gently into the cylinder, thus lifting the piston. This process continues until the piston comes to rest with the whole connected system reaching its final state of equilibrium. During this entire process, the air temperature in the rigid tank and the cylinder remains constant at 25 °C. (b) Find the mass of the air transferred…

Two different piston – cylinder devices each contain 1 kg of air. Initially, the temperature T = 300 K and %3D pressure P= 100 kPa of the gases are both the same in both cylinders. However, one of the cylinders is insulated and the other is not. Now, both of these gases inside the cylinders are let to expand in quasi- equilibrium processes until their pressures reach to 50 kPa. The expansion process takes place isentropically in the cylinder 1 and in the cylinder 2 the expansion process takes place reversible and isothermally. a) Plot in Excel the P-V diagrams of both processes. (Take k = cp / cv = 1.4) %3D b) Calculate the work done by the gases.
