Question

2.897 lb air is at 1 atm, 360 °R in a vertical piston-cylinder assembly. The air is compressed to state 2 at 111.6 atm, and 250.95 °R, and obeys the polytropic rule (pvⁿ= constant). During the process, 170 Btu releases from the process in the form of heat transfer. Determine:

The specific volume of the air at state 1 and state 2 in
The work of the process in Btu.
The specific internal energy of the air at state 2 in Btu/lb
If the area of the piston is 5 in.² and the mass of the piston is negligible, compute the force that exerts on the piston to maintain the pressure at state 2. Given that the atmospheric pressure is 1 atm.
