A single-stage axial flow turbine is to be designed for zero reaction without any
absolute swirl at rotor exit. At nozzle inlet the stagnation pressure and temperature of the gas are
424kPa and 1100K. The static pressure at the mean radius between the nozzle row and rotor
entry is 217 kPa and the nozzle exit flow angle is 70°.
Sketch an appropriate Mollier diagram (or a T - s diagram) for this stage allowing for the
effects of losses and sketch the corresponding velocity diagram. Hence, using Soderberg’s correlation
to calculate blade row losses, determine for the mean radius,
(i) the nozzle exit velocity,
(ii) the blade speed,
(iii) the total-to-static efficiency.
