At a particular ring of a reaction turbine having 50% degree of reaction, the blade speed is 70 m/s. The mass of steam is 5 kg/s. dry saturated at 1.5 bar. Both fixed and moving blades have inlet and exit angles of 35° and 20° respectively. Determine
(i) the power developed in kW by the pair of rings,
(ii) the blade height, which is to be one-tenth the mean blade ring diameter,
(iii) the heat drop by the pair if the steam expands with an efficiency of 80%
