The a two-row velocity compounded impulse wheel of steam velocity at nozzle outlet = 650 m/s, Mean blade speed = 125 m/s, Nozzle outlet angle = 16°. The Outlet angle first row of moving blades = 18°, Outlet angle fixed guide blades = 22°, and Outlet angle second row of moving blades = 36°. The steam flow = 2.5 kg/s. The ratio of the relative velocity at the outlet to that at the inlet is 0.84 for all blades. Determine the following:
(a) The axial thrust on the blades (10 marks)
(b) The power developed (10 marks)
(c) The efficiency of the wheel (10 marks)
(d) Draw the blade velocity diagram (10 marks)
