Consider an ideal Brayton cycle with reheat (air standard). Thepressure and temperature of the air at the inlet of the gas turbineis 1200 kPa and 1000 K respectively. Assume the gas expands to 100kPa in two stages. Between the stages, the air is reheated at aconstant pressure of 350 kPa to 1000 K. Assume a fully isentropicprocess in the turbines.
Find:
(a) the work produced at each stage, in kJ/kg of air flowing.
(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.
