1. A Turbofan engine with three spools operates at Fan (LP compressor) IP compressor HP compressor IP turbine LP turbine HP turbine www Low pressure (LP) intermediate pressure OP High pressure (HP) Three-shaft configuration Mo 0.85, po 26.5 kPa, To=223.3 K, intake air mass flow, mo-780 kg/s, Bypass ratio, a = 6, Bypass duct pressure loss = 5%, d= 0.95, e fan(LPC) = 0.79, Tan(LPC) 1.5, PC = 0.80, TIPC = 6.5, THPC=0.82, HC 4.2, Turbine entry temperature= 1750 K, Combustor pressure loss= 5%, 1Combustor = 0.97, hPR 42500 kJ/kg K, THPT=0.92, IPT=0.90, LPT=0.88, nozzle = 0.98, Ye = 1.4, Cpc = 1.005 kJ/kg K, y₁= 1.33, Cpt = 1.150 kJ/kg K, nm.LP=0.98, m.IP=0.95, 1m.HP=0.93 . LPC: Low pressure compressor, IPC: Intermediate pressure compressor, HPC: High pressure compressor . • LPT: Low pressure turbine, IPT: Intermediate pressure turbine, HPT: High pressure turbine Check whether the converging nozzle is chocked and calculate (a) Total pressures and temperatures at each inlet and outlet of component throughout the engine (b) Exit velocity (c) Thrust (d) Thermal and propulsive efficiencies
