Inflow at the rate of 3.5 m3/s enters a reservoir at the water spread area of 8 km2.

Question

Determine the time required?

 

for the reservoir to fill up for a depth of 10 cm.
Thank you for the person who tries this question.

Answer 1

Calculate the volume of the reservoir,

V=Ah

  =8*(10^3)^2 m^2 * 0.1 m

  =8*10^5 m^3

 

Calculate time required, 

t=volume/flow rate

   =8*10^5 /3.5

   =228571.43 s

   =63.49 h
