Question

2. A water tank is being emptied. It’s x-sectional area is 0.3 m2. It is 4m+Y high. There are
two openings. One at the middle height (2 m+Y/2) and one at the bottom. The openings
have area of 0.0015 m2 each. How long it will take to empty the tank when it starts full.
Assume Cd as 0.6. You first must clearly derive the expression for time required for
emptying the tank. (Y is last 2 digits of your ID in cm)
