Description: Relationship between the pump efficiency and the rate of flow at given operating conditions of speed and liquid; Name: characteristics of pump efficiency
Description: relationship between the total head of the pump and the rate of flow at given operating conditions /rated conditions of speed and liquid; Name: Pump efficiency curve
Description: Speed that characterizes a pump in terms of its speed, flow rate per impeller eye, i.e. total flow for single-flow impeller, half flow for double-flow impeller, at the best efficiency point and head per stage at maximum impeller diameter ; Name: Specific speed
