A cylindrical tank with a height is filled with water up to its brim. (a) what time is required to empty the tank through an orifice at its bottom it the cross-sectional area of the orifice is that of tank? (b) Compare this time with that required for the same volume of water to flow out of the tank if the water level in the tank is maintained constant at a height from the orifice.

(a) Time taken to empty the tank (has been derlved in theory) is:
Substituting the values we have,
(b) Rate of flow of water constant
Total volume of water
TIme take to empty the tank with constant rate
