Flow or discharge: It is a measure of volume capacity of a pump. It can be expressed as GPM -+Gallon per Minute, or l/min etc.
+Pump performance curve: The diagram which explain the relationship between the head, power, efficiency, and discharge. The manufacturer will +Supply the curve. +Pipe friction loss: The friction loss is the major loss of a flowing fluid. +Pressure The force exerted on the walls of a pipe by the liquid. It is measured in PSI, barg, kgf/cm2. +Efficiency Total power output to the total power input, it is expressed as a percentage.
