Answer:
So reservoir will take 455000 sec to raise 35 cm
Explanation:
We have given surface area of the reservoir = 650000 [tex]m^2[/tex]
Rate of flow = 0.5 m/sec
Height through which reservoir is raise = 35 cm = 0.35 m
So volume [tex]\Delta V=surface\ area\times height=650000\times 0.35=227500m^3[/tex]
We have to calculate the time
Time is given by [tex]t=\frac{\Delta V}{rate\ pf\ flow}=\frac{227500}{0.5}=455000sec[/tex]
