Theory + Problem on Regeneration Rankine cycle ( open feed water heater) Thermodynamic vapour cycle

Описание: 1. How to draw Pressure-Volume and Temperature-Entropy diagram for Regeneration Rankine cycle.

2. Solve 1 Problem on Regeneration Rankine cycle by using Mollier diagram and steam table .


Consider a regenerative vapour power cycle with feed water heater. The steam enters the turbine at 80 bar and 500°C and expands to 7 bar, Where some of the steam is xtracted and diverted to feed water heater operating at 7 bar. The remaining steam expands through a second stage turbine to a condenser pressure of 0.08 bar. The saturated liquid exits the fed water heater at 7 bar.
Calculate
1. Enthalpies at different points
2. Low pressure pump work and High pressure pump work
3. Mass of steam extracted from Turbine
