Question

What are the four processes of the Rankine Cycle?

Answer 1

Rankine Cycle:

1. If water travels through the four components without irreversibilities or pressure drops, the Rankine cycle is a perfect cycle.
2. According to the T-S diagram given below, the ideal Rankine cycle consists of four processes
   1. Process 1-2:
      1. Isentropic compression in a pump.
      2. The working fluid is pushed from low to high pressure in this chamber.
   2. Process 2-3:
      1. Heat addition at constant pressure in the boiler.
      2. The high-pressure liquid is introduced to the boiler and cooked at constant pressure to become a dry saturated vapour in this process.
   3. Process 3-4:
      1. Isentropic expansion in a turbine.
      2. Power is generated as the dry saturated vapour expands through the turbine.
   4. Process 4-1:
      1. Heat rejection under constant pressure in a condenser.
      2. A saturated liquid is formed by condensing wet vapour at a steady pressure.
