b) Water is supplied to an axial flow lurbine under a total had of 35 m. The mean diameter of the runner is 2 mohd it rotates at 145 apni. Water leaves the guide vanes at 30° to the direction of runner potation and ul mean radius, the angle of the runner blades at outlet in 28°. If 7% of the total head is lost in the casing and guide vanes, and the relative velocity is reduced by 8% due to friction in the runner, determine the blade angle at inlet (at mean radius) and the hydraulic efficiency of the turbine, (12 marks)
