Textbook Problem

Water in an open bowl evaporates at a rate proportional to the area of the surface of the water. (This means that the rate of decrease of the volume is proportional to the area of the surface.) Show that the depth of the water decreases at a constant rate, regardless of the shape of the bowl.

To determine

**To show:**

The depth of the water decreases at a constant rate regardless of the shape of the bowl.

Explanation

The rate of change of volume of water is given as

where

The rate of change of the depth of water with respect to time is

By the Chain rule,

From equation (1),

The total volume of water up to
