An industrial gas turbine operates at an 8.8:1 pressure ratioand a mass flow of 77 kg/s. The
exhaust temperature is at 437?C and the inlet temperature to themachine is around 1000?C.
The machine is to be designed for a constant axial velocity of 200m/s. (This data is based on
the Rolls-Royce Avon, an engine that dates from the 1950s but isstill used as low efficiency
high reliability engine for stationary power such as pipelinepumping.)
For this gas turbine, draw to scale the meridional view with:
(a) a constant mean radius of 0.4 m.
(b) a constant outer diameter (to minimise cross sectional area) of1.05 m.
