Question:
A centrifugal pump has an impeller of cm outer diameter and cm inner diameter. When running at rpm the pump discharges liters of water per second against a gross head of m At this discharge, water enters the impeller without stock. The vane angle at outlet is deg to the tangent at outlet, and the outlet, and the area of flow which is constant from inlet to outlet of the impeller is m Determine a The manomertic efficiency of the pump and b The loss of head at inlet to the impeller when the discharge is reduced by the speed of rotation being unchanged
