The water in the 40-ton capacity tank A, which is 20 m below the ground level, is transferred to the B tank, which is 30 m above the ground level, by means of a line and pump every 12 hours. Since it is known that the pipes under the ground are made of coarse concrete with a diameter of DN100, and the pipes above ground level are made of plastic material with a diameter of DN40, find the pump power (W).

 

Note: Determine the Darcy friction factor for pipes using the Colebrook equation. You need to write down the iterations you use in the equation in detail.
