An inward flow reaction turbine has external and internal diameters as 1.095 m and 0.553 m respectively. The turbine is running at 210 R. P. M. The velocity of flow through the runner remains constant and is equal to 2.0 m/s. The width of the turbine at inlet is 241 mm. The guide blades make an angle of 10.5o to the tangent of the wheel. If the discharge of the turbine at the outlet is radial determine the following: i) Draw the inlet and outlet velocity diagrams ii) The absolute velocity of the water at the inlet of the runner. iii) The velocity of whirl at inlet
