Hot Water Suply

Rule I. —To find the new volume of a quantity of water at a given temperature, multiply the original volume by the comparative volume, taken from Table II, at the new temperature. Divide the product by the comparative volume, taken from Table II, at the original temperature.

Rule II.—To find the change in volume of a given quantity of water, due to a change of temperature, take the difference between the new volume found by rule I and the original volume.

EXAMPLE 1.—A vertical cylindrical vessel contains 40 United States standard gallons of water heated from 62° F. to 200° F. What is the new volume of the water, in cubic inches?

SOLUTION.SOLUTION.—The original volume is 40x231=9,240 cu. in. By Table II, the comparative volume at 62° = 1.00101, and at 200° = 1.03889. By rule I,
