Given:
Height of tank = 8 ft
and we need to pump fuel weighing 52 lb/ to a height of 13 ft above the tank top
Solution:
Total height = 8+13 =21 ft
pumping dist = 21 - y
Area of cross-section = =
=16
Now,
Work done required =
=
= 832)
= 113152 = 355477 ft-lb
Therefore work required to pump the fuel is 355477 ft-lb
