One kg of air is in a piston-cylinder assembly. Air is modeled as an ideal gas with a constant specific heat ratio, k = 1.4. The air undergoes a power cycle consisting of four processes in series: Process 1-2: Constant-temperature expansion at 600 K from P, = 0.5 MPa to P2 = 0.4 MPa Process 2-3: Polytropic expansion with n=k to P; - 0.3 MPa Process 3-4: Constant-pressure compression to V4-V Process 4-1: Constant-volume heating. (a) Sketch the cycle on...

A rigid well insulated container holds 1 kg of dry air
at P1= 5 MPa.
5. A rigid well-insulated container holds 1 kg of dry saturated steam at P = 5 MPa. At some point in time, a tiny crack develops in the uppermost region of the container. Through this crack, some of the H2O escapes slowly into the atmosphere until the pressure inside the container falls to P2 = 1.5 MPa. This leakage process is slow enough so that...

A piston-cylinder assembly contains air modeled as an ideal gas with a constant specific heat ratio, k = 1.4. The air undergoes a power cycle consisting of four processes in series: Process 1-2: Constant-temperature expansion at 600 K from p1 = 0.5 MPa to p2 = 0.4 MPa. Process 2-3: Polutropic expansion with n = k to p3 = 0.3 MPa. Process 3-4: Constant-pressure compression to V4 = V1. Process 4-1: Constant volume heating. Sketch the cycle on a p-v...

7. An industrial turbine process requires a steady 0.5 kg/s of air at 200 kPa. This air is to be the exhaust from a specially designed turbine with inlet state 400 kPa, 400 K. The heat transfer could be obtained from a source at 500 K if necessary. This process may be assumed to be reversible and the changes in kinetic and potential energy are negligible. Air is an ideal gas, with constant specific heats, using Table A.S (a) Which...

PROBLEM-3 (30%) One kg of air in a piston-cylinder assembly undergoes two processes in series from an initial state where P1 = 0.5 MPa, T1 = 227°C: Process 1-2: Constant-temperature expansion until the volume is twice the initial volume. Process 2–3: Constant-volume heating until the pressure is again 0.5 MPa. Sketch the two processes in series on a P-v diagram. Assuming ideal gas behavior, determine: (a) the pressure at state 2, (in MPa) (b) the temperature at state 3, (in...
