A mass of 4 kilograms of carbon dioxide (CO2) in a piston-cylinder assembly undergoes two processes in series from an initial state where p1 = 0.5 MPa, T1 = 267°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. Assuming ideal gas behavior, determine (a) the pressure at state 2, in MPa, (b) the temperature at state 3, in oC, and for each of the processes (c) the work and heat transfer, each in kJ.

Explanation:

A large dynamometer operates a pump that circulates a viscous fluid through a restrictive fluid circuit. ... Under Steady Operating Conditions, Heat Loss From The Fluid Is Measured As 150 KW When The Shaft Is Rotating At 1000 Rpm, And 275 KW When The Shaft Speed Increases To 2000 Rpm. The Pump Efficiency Varies ...
