Question

A gas turbine plant receives air at 1 bar and 200c. If the maximum pressure and temperature of the hot gases in the plant are 25 bar and 9000c, find the power developed and thermal efficiency of the plant. Take mass flow rate of air and specific heat at constant pressure as 2 kg/s and 1kj/kgk. If a reheater is used and the exhaust gases from the first turbine are reheated to 7000c and then expanded in a secondary turbine. Find the increase in power developed and thermal efficiency of the plant. Draw the p-v & t-s diagrams. State your assumptions if any
