Various Efficiencies Of A Centrifugal Pump Are Related As (Where, Εm = Mechanical Efficiency Εv = Volumetric Efficiency. Εma = Manometric Efficiency Εo = Overall Efficiency) ?

Various Efficiencies Of A Centrifugal Pump Are Related As (Where, Εm = Mechanical Efficiency Εv = Volumetric Efficiency.

Ηv = Ηm × Ηma

Ηma = Ηm × Ηv

Ηm = Ηv . Ηma

Ηma × Ηm × Ηv = Ηo
