Q1)
How do the inefficiencies of the turbine and the compressor affect
(a) the back-work ratio and (b) the thermal efficiency of a
gas-turbine engine? Q2) The nozzle of a single stage impulse
discharges the working fluid at an angle of 25° to the plant of
rotation of the blades. The fluid living the blades with an
absolute velocity of 290 m/s and a trailing angle of 60° to the
plane of rotation. The blades have equal inlet and outlet...
