7. assume you are dealing with a vertical walled reservoir having a surface area of 650,000 mwith an inflow of 0.5 m/s. how many hours will it take to raise the reservoir by 35 cm? (3 marks)

So reservoir will take 455000 sec to raise 35 cm

Explanation:

We have given surface area of the reservoir = 650000

Rate of flow = 0.5 m/sec

Height through which reservoir is raise = 35 cm = 0.35 m

So volume

We have to calculate the time

Time is given by
