The tank in the shape of a semicircle is fileld with crude oil to a depth of 2 meters. The oil has a density of 875 kg/m3. Write an integral which calculates the work required to pump the oil of of the outlet.
The tank has a radius of 3 m, a 4 m spigot, a depth of 17 m.
I got W=((1/2)Πx32x17x875x9.8 0∫7(17-y) +4 dy
Would this be right?
