A piston-cylinder device contains 5 kg of refrigerant- 134a at 800 kPa and 70°C. The refrigerant is now cooled at constant pressure until it exists as a liquid
A piston-cylinder device contains 3 ft3 of air at 60 psia and 150°F. Heat is transferred to the air in the amount of 40 Btu as the air expands isothermally.
A piston/cylinder contains helium at 110 kPa at ambient temperature 20°C, and initial volume of 20 L. The stops are mounted to give a maximum volume
A piston/cylinder contains butane, C4H10, at 300°C, 100 kPa with a volume of 0.02 m3. The gas is now compressed slowly in an isothermal process to 300 kPa.
A piston/cylinder contains R-12 at -30°C, x =20%. The volume is 0.2 m3. It is known that V stop=0.4 m3, and if the piston sits at the bottom, the spring force
A piston/cylinder has 1 kg of R-134a at state 1 with 110°C, 600 kPa, and is then brought to saturated vapor, state 2, by cooling while the piston is locked
A piston/cylinder has 2 kg ammonia at 50°C, 100 kPa which is compressed to 1000 kPa. The process happens so slowly that the temperature is constant.
A piston/cylinder has 2 kg water at 1000 kPa, 250°C which is now cooled with a constant loading on the piston
A piston/cylinder has nitrogen gas at 750 K and 1500 kPa. Now it is expanded in a polytropic process with n = 1.2 to P = 750 kPa.
A piston/cylinder has 0.5 kg air at 2000 kPa, 1000 K as shown. The cylinder has stops so Vmin = 0.03 m3.
A piston/cylinder device keeping a constant pressure has 1 kg water at 20oC and 1 kg of water at 100oC both at 500 kPa separated by a thin membrane
A piston/cylinder with cross sectional area of 0.01 m2 has a piston mass of 100 kg resting on the stops. With an outside atmospheric pressure of 100 kPa
A piston/cylinder with constant loading of piston contains 1L water at 400 kPa, quality 15%. It has some stops mounted so the maximum possible volume is 11L.
A piston/cylinder setup contains air at 100 kPa, 400 K which is compressed to a final pressure of 1000 kPa
A piston/cylinder of cross sectional area 0.01 m2 maintains constant pressure. It contains 1 kg water with a quality of 5% at 150oC
A piston/cylinder initially contains propane at T = -7°C, quality 50%, and volume 10L. A valve connecting the cylinder to a line flowing nitrogen gas
A piston/cylinder in a car contains 12 in 3 of air at 13 lbf/in 2, 68 F. The air is compressed in a quasi-equilibrium polytropic process with polytropic
A piston/cylinder arrangement contains 10 g of air at 250 kPa, 300°C. The 75-kg piston has a diameter of 0.1 m and initially pushes against the stops
A piston/cylinder contains 0.1 kmol hydrogen and 0.1 kmol Ar gas at 25°C, 200 kPa. It is heated up in a constant pressure process so the mole fraction of atomic
A piston/cylinder with cross-sectional area of 0.1 ft2 has a piston mass of 200 lbm resting on the stops. With an outside atmospheric pressure of 1 atm
A piston/cylinder assembly contains 1 kg of liquid water at 20oC and 300 kPa. There is a linear spring mounted on the piston such that when the water is heated
A piston/cylinder arrangement is loaded with a linear spring and the outside atmosphere. It contains water at 5 MPa, 400°C with the volume being 0.1 m3
A piston/cylinder arrangement has the piston loaded with outside atmospheric pressure and the piston mass to a pressure of 150 kPa
A piston/cylinder arrangement contains water of quality x = 0.7 in the initial volume of 0.1 m3, where the piston applies a constant pressure of 200 kPa.
A piston/cylinder contains 1 kg of liquid water at 20?C and 300 kPa. There is a linear spring mounted on the piston such that when the water is heated
