As we discussed in concept

Torricelli's Theorem / Velocity of Efflux -

In fluid dynamics relating the speed of fluid flowing out of an orifice. 

- wherein

 

 Water flow out in t sec when water filled up to a height h.

\therefore if water is filled to a height 16, water will flow out in

\\t=\frac{A}{A_o}\:\sqrt{\frac{2H}{g}}\:\\\:\frac{t_{2}}{t_{1}}=\sqrt{\frac{16h}{h}}=4\:\:\:\Rightarrow t_{2}=4t


Option 1)

t

This option is incorrect.

Option 2)

4t

This option is correct.

Option 3)

2t

This option is incorrect.

Option 4)
