If a pump is capable of lifting 5000kg of water... - JAMB Physics 2013 Question
If a pump is capable of lifting 5000kg of water through a vertical height of 60m in 15 min, the power of the pump is
A
2.2.5 x 10 5js-1
B
2.5 x 104js-1
C
3.3 x 103js-1
D
3.3 x 102js-1
correct option: c
P = \(\frac{mgh}{t}\)
P = \(\frac{5000 \times 10 \times 60}{(15 \times 60)s}\)
P = 3333.3333
P = 3.3 x 103js-1
P = \(\frac{5000 \times 10 \times 60}{(15 \times 60)s}\)
P = 3333.3333
P = 3.3 x 103js-1
