|In a gas-turbine power plant. there is a limit on the maximm temperature at the turbine inlet imposed by metallurgical considerations of tlie turbine blades, In order to increase the efficiency, one consideration is to increase the conmpressor pressure ratio keeping the turbine inlet temperature constant. Increasing the compressor pressure ratio will also decrease the net work developed per unit mass flow rate, Consider a gas-turbine power plant operating on a simple Brayton Cycle with air as the working fluid. The air enters the turbine at 1100 K and leaves at 110 kPa and 660 K. Heat is rejected to the surroundings at a rate of 6750 kJ/s, and air flows through the cycle at a rate of 18 kg/s. Assuming both the turbine and the compressor to be isentropic. determine the best compression ratio for optimum efficiency and net work per unit mass flow rate of the plant. To solve this problem, you are asked to design a compression #3aio of a gas-turbine power plant that will provide the best…
