A gas turbine plant envisaged to be installed to provide power to the University of Nigeria Nsukka is designed to take in air at 290K and 1.01bar with a pressure ratio of 8/1. The arrangement of the system components is made in such a way that allows the compressor to be driven by the high pressure (HP) turbine and a separate power shaft by the low pressure (LP) turbine. Design parameters show that the isentropic efficiencies of the compressor, the low-pressure turbine (LP) and the high-pressure turbine (HP) are 80\%, 83\% and 85\% respectively. As a mechanical engineering student of the University, you have been asked to: i. Draw a detailed schematic of the turbine plant ii. Also draw the equivalent T-S diagram and to calculate the: iii. Work input to the compressor iv. Work output from the HP turbine v. Intermediate pressure after expansion from the HP turbine vi. Work output from the LP turbine vii. Net power output per Kg/s mass flow viii. The work ratio ix. The heat supplied to the turbine and x. The cycle efficiency Parameters obtained for the plant indicate the following: Cp for the compression process 1.005kJ/kg K; k=1.4; Cp for the combustion and expansion processes 1.15kJ/kg K; gamma = 1.333
