A) \[4\,{{m}^{3}}\]
B) \[0.1\,{{m}^{3}}\]
C) \[2.0\,{{m}^{3}}\]
D) \[2.4\,{{m}^{3}}\]
Correct Answer: D
Solution :
Power of pump = 4000 watt, \[g=10\,m\text{/}{{s}^{2}},\] \[h=10\,m,\] \[t=60\,\sec \] \[P=\frac{mgh}{t}\]or \[m=\frac{Pt}{gh}\] \[m=\frac{4000\times 60}{10\times 10}=2400\,kg\] Now, volume\[=\frac{\text{mass}}{\text{density}}=\frac{2400}{1000}=2.4\,{{m}^{3}}\]You need to login to perform this action.
