Formulas


H = [ P + V 760 ] × 10 5 ρ g + Z

Q = A x h t

OP = ρ g Q H

I P = n × 3600 × η E × T

η pump = OP IP × 100%

Provided Data

Measuring Area in collecting tank (A) = 0.3 × 0.3  m2
Datum head, (Z) = 0.3  m
Density of oil, (ρ) = 860  kg/m3
Energy meter constant in Rev/kWh, (Ec) = 1200 Rev/kWh
Efficiency of motor, (ηm) = 0.80
Number of revolutions taken in energy meter, (n) = 3
