Air enters the turbine of a gas turbine at 1400 kPa, 1400 K, andexpands to 100 kPa in two stages. Between the stages, the air isreheated at a constant pressure of 350 kPa to 1400 K. The expansionthrough each turbine stage is isentropic.

Determine:

(b) the heat transfer for the reheat process, in kJ/kg of airflowing.

(c) the increase in net work as compared to a single stage ofexpansion with no reheat.
