Question: In the friction-free piston-cylinder assembly, initially there is a volume of 0.1 m³ air at 300 K temperature. The air is heated at a constant pressure of 300 kPa, at a constant piston velocity and a temperature of 600 K for 30 s. In this context, calculate the power to be given to the piston as [kW]. Show the process in the diagram T (° C) - v (m³ / kg).

Air in a piston-cylinder assembly undergoes a polytropic expansion in which the pressure – specific volume relation is p. V..2=constant. The initial volume is 0.5 m², the initial temperature is 500 K and initial pressure is 600 kPa. The final pressure is 300 kPa. Determine (a) the mass of air, in kg (b) the boundary work, in kJ (c) the final temperature in K and (d) the heat transfer, in kJ.
Arigid tank of volume 0.5 m3 is connected to a piston-cylinder assembly by a valve as shown in the diagram below. Both vessels contain pure water. They are immersed in a constant- temperature bath at 200°C and 600 kPa. Consider the tank and the piston-cylinder as- sembly as the system and the constant-temperature bath as the surroundings. Initially the valve is closed, and both units are in equilibrium with the surroundings (the bath). The rigid tank contains saturated water with...

1 kg air in a piston-cylinder assembly is heated at constant pressure, resulting the expansion of the volume. The initial temperature of the air was 300 K, and the air temperature becomes 500 K after the expansion. What is the boundary work done by the air? Assume that air is an ideal gas with constant specific heats ( 0.718 v c = kJ/kg-K and 1.005 p c = kJ/kg-K)..
3.111 Air contained in a piston-cylinder assembly contains air, initially at 2 bar, 300 K and a volume of 2 m^3.
