question

Suppose that a tank containing a certain liquid has an outlet near the bottom. Let h(t)h(t) be the height of the liquid surface above the outlet at time tt. Torricelli's principle states that the outflow velocity vv at the outlet is equal to the velocity of a particle falling freely (with no drag) from the height hh. Consider a water tank in the form of a right circular cylinder that is $3 \mathrm{~m}$ high above the outlet. The radius of the tank is $1 \mathrm{~m}$ and the radius of the circular outlet is $0.1 \mathrm{~m}$. If the tank is initially full of water, determine how long it takes to drain the tank down to the level of the outlet.
