Torricelli's Law A tank similar to the one in Exercise 6 has a height of 20 feet and a radius of 8 feet, and the valve is circular with a radius of 2 inches. The tank is full when the valve is opened. How long will it take for the tank to drain completely?

To determine

**To calculate:** The time takenby the tank to drain completely if the height of cylindrical tank

Explanation

**Given:**

The height of cylindrical tank

**Formula used:**

One of the forms of the Torricelli’s Law is:

**Calculation:**

According to the Torricelli’s Law:

where

Since a circular valve of the radius of

As

Then,

Now, since the tank is cylindrical so the cross-sectional area of the tank remains constant at all heights.

So, at any height, the cross-sectional area is:

According to Torricelli’s Law.
