A piston-cylinder device contains 2 lbm of refrigerant- 134a at 120 psia and 100°F. The refrigerant is now cooled at constant pressure
A piston-cylinder device contains 1.2 kg of saturated water vapor at 200°C. Heat is now transferred to steam, and steam expands reversibly
A piston-cylinder device contains 1.2 kg of nitrogen gas at 120 kPa and 27°C. The gas is now compressed slowly in a polytropic process
A piston-cylinder device contains 0.8 kg of steam at 300°C and 1 MPa. Steam is cooled at constant pressure until one-half of the mass condenses.
A piston-cylinder device contains 0.5 lbm of water initially at 120 psia and 2 ft3. Now 200 Btu of heat is transferred to the water while its pressure is held
A piston-cylinder device initially contains 0.07 m3 of nitrogen gas at 130 kPa and 120°C. The nitrogen is now expanded polytropically to a state of 100 kPa
A piston-cylinder device contains an ideal-gas mixture of 3 kmol of His gas and 7 kmol of Ar gas at 50°C and 400 kPa.
A piston-cylinder device contains 5 kg of saturated water vapor at 3 MPa. Now heat is rejected from the cylinder at constant pressure
A piston-cylinder device contains 5 kg of air at 400 kPa and 30°C. During a quasi-equilibrium isothermal expansion process, 15 kJ of boundary work
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 50 kg of water at 200 kPa with a volume of 0.1 m3. Stops in the cylinder are placed to restrict the enclosed volume to 0.5 m3 similar
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
