Question

oil is pumped from the tank of a ship to a storage tank on land 45m higher in elevation. what is the power required to pump twenty thousand litres of oil per hour given that one litre of oil has a mass of 0.8 kilogram

Answer 1

The power required to pump 20000 L oil is 1962 watts.

Explanation:

Power = hAγQ  

Where:

• hA = energy added to the fluid [m]
• γ = specific weight of the fluid [N /m^3]
• Q = volume flow rate [m^3 / s]

Solution:

Q = (20000 L/hr)(m^3 / 1000 L)(hr / 3600 sec) = 0.005556 m^3 / sec

γ = ρg

Where ρ is fluid density and its unit is kg / m^3.

γ = ρg = (0.8 kg / L)(1000 L / m^3) (9.81) = 7848  N / m^3

Power =  hAγQ  

P = 45 x 7848 x 0.005556 = 1962 watts

Thus the power required to pump 20000 L oil is 1962 watts.
