An inward flow reaction turbine is working under a head of 15 m with a speed of 300 rpm. The inner and outer diameters of the runner are 500 and 750 mm respectively. The runner internal width at inlet is 70 mm and the blades occupy 10% of the runner passage. The radial component of the fluid velocity is constant from inlet to outlet and is equal to 0.2./2gh. Water leaves the whcel radially. The blading efficiency is 95% and the overall efficiency of the turbine is 85%. Draw the velocity triangles and calculate: i. The angle of the guide vanes ii. The angles of the moving vanes at inlet and outlet iii. The water flow rate iv. The width of the runner at outlet V. The power developed
