A piston-cylinder device contains 5kg of steam at 100 degrees C with a quality of 40%. The steam undergoes the following processes: 1-2 Heat is transferred to the steam in a reversible manner while the temperature is held constant until the steam becomes a saturated vapor. 2-3 The steam expands in an adiabatic, reversible process until the pressure is 40 kPa. Sketch these processes with repect to the saturation lines on a single T-s diagram. Determine the amount of heat transferred to the steam in process 1-2. Determine the work done by the steam in proccess 2-3.

Question

A piston-cylinder device contains 5kg of steam at 100 degrees C with a quality of 40%. The steam undergoes the following processes:

1-2 Heat is transferred to the steam in a reversible manner while the temperature is held constant until the steam becomes a saturated vapor.

2-3 The steam expands in an adiabatic, reversible process until the pressure is 40 kPa.

  • Sketch these processes with repect to the saturation lines on a single T-s diagram.
  • Determine the amount of heat transferred to the steam in process 1-2.
  • Determine the work done by the steam in proccess 2-3.
