The overall efficiency of a centrifugal pump is:

AProduct of manometric and mechanical efficiencies

BRatio of manometric efficient to mechanical efficiency

CProduct of manometric and hydraulic efficiencies

DRatio of mechanical efficiency to manometric efficiency

Answer:

A. Product of manometric and mechanical efficiencies

Read Explanation:

Overall Efficiency ( eta ) is defined as a ratio of the power output of the pump to the power input to the pump

ie

Product of manometric and mechanical efficiencies ηo=ηmano×ηm\eta_o=\eta_{mano}\times \eta_m
