A piston cylinder device contains air with a volume of 0.05 m3 at 25oC and 100 kPa pressure. The gas is now compressed to a final temperature of 95oC at 250 kPa. This compression is polytropic and follows PVn=constant.

a. Determine how much boundary work was added to the gas [in kJ]

b. How much heat was added or removed from this system during this process? [in kJ]

In a cylinder/piston arrangement, air is compressed in a reversible polytropic process to a final state of 800 kPa, 500 K. Initially air is at 110 kPa and 25oC. During the compression process heat transfer takes place with the ambient maintained at 25oC. Assume air as an ideal gas (R =0.287 kJ/kg) and has constant specific heats of Cp = 1.004 kJ/kgK and Cv = 0.717 kJ/kgK. If the mass of air in the cylinder is 0.1286 kg, determine a)...

A piston cylinder device contains 0.15 kg of air initially at 2 MPa and 350 C. First, the air expands isothermally to a pressure of 500 kPa. Then, it is compressed polytropically back to the initial pressure (2 MPa) with a polytropic exponent of 1.2. Find the work performed or introduced by or to the air for each process. Express it both times in kJ.

A 0.2 m3 piston-cylinder initially contains 400 K air. A heavy frictionless piston maintains a pressure of 500 kPa abs. Then, a weakness in the cylinder wall blows out and creates a hole. Air escapes through the hole until the piston drops far enough to cover the hole. At that point, the volume is half the initial volume. During this process, 75 kJ of heat is transferred to the 100 kPa, 300 K surroundings. Using Cp = 1.005 kJ/kg-K and...
