Propane is compressed from an initial state with a pressure of 100 lbf/in2 and a quality of 0.40 to a final saturated liquid state with a temperature is 50°F. Is it possible for this process to occur adiabatically? Justify your answer. Air is contained in a rigid, well-insulated container of volume 3 m3. The air undergoes a process from an initial state with a pressure of 200 kPa and temperature of 300 K. During the process, the air receives 720...

A frictionless piston/cylinder apparatus 100 mm in diameter contains water vapor with a quality of 20%. The piston, which has a mass of 16 kg, is floating on the vapor 50 mm above the bottom of the cylinder. Stops above the piston prevent it from moving upward more than 30 mm. Heat is added until the temperature reaches 400?C. Find: a. the initial pressure b. the mass of water c. the quality when the piston hits the stops d. the...

4) The work produced by a piston-cylinder device depends on the pressure inside the cylinder and the amount the piston moves, resulting in a change in volume inside the cylinder. Mathematically In order to integrate this equation, we need to understand how the pressure changes with the volume. We can model most combustion gases as air and assume that they follow the ideal gas law PV- nRT where P- pressure, kPa, volume, m n- number of...

Air undergoes two processes in series:
PROBLEM 1Air undergoes two processes in series:Process 1-2: Polytropic compression, with n = 1.3, from p1 = 110 kPa, V1 = 0.5 m3 to V2 = .1 m3Process 2-3: Constant pressure process to V3 = V1Determine the work done in each process and comment on the direction of work. Then, determine the net work from Process 1 - 3. (You may assume air to behave as ideal gas throughout process)PROBLEM 2 Air is compressed isothermally in a piston cylinder. If the initial...

is at a pressure of 1.00×105Pa, has a temperature of 300K, and
occupies a volume of 1.50L. The gas then undergoes two processes.
In the first, the gas is heated and the piston is allowed to move
to keep the temperature equal to 300K. This continues until the
pressure reaches 2.50×104Pa. In the second process, the gas is...
