Transcribed Image Text:

The superheated steam at 510 °C is expanded in the first turbine stage, and exit as saturated at 0.7 MPa pressure. Then the steam is reheated at this pressure to its initial temperature, before it expanded in the second turbine stage to condenser pressure, as saturated steam again. a) Draw a well-labelled T-s diagram, and determine the b) Pressure of the steam at the inlet of the first turbine stage, in bar c) Pressure of the steam at the exit of the second turbine stage, in bar d) Work done in each turbine stage per unit of steam flow in the boiler, in kJ/kg e) Amount of heat added during the reheat per unit of steam flow in the boiler, in kJ/kg The superheated steam at 510 °C is expanded in the first turbine stage, and exit as saturated at 0.7 MPa pressure.
