Liquid water is pumped at a volumetric flow rate of 0.02 m3s-1 from Tank I to Tank II, as shown in the figure.
Both the tanks are open to the atmosphere. The total frictional head loss for the pipe system is 1.0 m of water. In addition, use the following data and assumptions
• Density of water is 1000 kg m-3
• Acceleration due to gravity is 9.81 m s-2
• Efficiency of the pump is 100%
• The liquid surfaces in the tanks have negligible velocities
The power supplied (in W) by the pump to lift the water is _______ (round off to 1 decimal place).
