Regeneration, Reheat, and Compression with Intercooling
Reconsider Problem 9.70 and include in the analysis that each turbine stage might have an isentropic efficiency less than 100%. Plot each of the quantities calculated in parts (a) through (c) of Problem 9.70 for values of the interstage pressure ranging from 100 to 1200 kPa and for isentropic efficiencies of 100%, 80%, and 60%.
9.70 Air enters the turbine of a gas turbine at 1200 kPa, 1200 K, and expands to 100 kPa in two stages. Between the stages, the air is reheated at a constant pressure of 350 kPa to 1200 K.
The expansion through each turbine stage is isentropic. Determine, in kJ per kg of air flowing,
(a) the work developed by each stage.
(b) the heat transfer for the reheat process.
(c) the increase in net work as compared to a single stage of expansion with no reheat.
