Efficiency of the pump is derived from the following
formula.
First BHP of the pump is calculated .
BHP = Q*H *Sp.gravity of the liquid pumped, divided by
367.2 * efficiency of the pump.
Then for calculating the power of driver required to pump,
is calculated by
HP = Q*H*Sp.gravity of liquid /367.2*effciency of
pump*efficency of motor.
Now efficiecny of the pump is calculated from the above as
= HP of motor * efficiency of motor *367.2 / Q*H*Sp.gravity
