An intermediate pressure steam turbine is to bedesigned with 7 repeating stages as described above. The inletconditions are: total temperature = 550°, total pressure = 4.0MN/m2. The exit total pressure is 0.5 MN/m2. The rotational speedof the turbine is to be 1500 rev/min and the power output requiredis 90 MW. It is estimated that the turbine efficiency will be 90%.Calculate the mass flow through the turbine, the axial velocity,mean blade speed and the mean diameter of the turbine.
