Useful Information 
A gallon of water equals 231 cubic inches 
and weighs 8 1/3 pounds. A cubic foot of 
water equals lYl gallons and weighs 621/2 
pounds. 
Water expands 1/11 of its bulk in freezing. 
One cubic inch of water evaporates into a 
cubic foot of steam. To evaporate one cubic 
foot of water requires the consumption of l/i 
pounds of coal, or about one pound of coal 
to a gallon of water. Each nominal horse- 
power of a boiler requires 30 to 35 pounds of 
water per hour. 
One inch of rainfall means 100 tons of 
water on every acre. 
A column of water 2 3/10 feet high equals 
one pound per square inch pressure. To find 
the pressure per square inch of a column of 
water, multiply the height of the column in 
feet by the decimal .434. 
Doubling the diameter of a pipe or cylin¬ 
drical vessel increases its capacity four times. 
Double-riveting is from 16 to 20 per cent

tiply the diameter by 3.1416. 
To find the diameter of a circle, multiply 
the circumference by .31831. 
To find the area of a circle, multiply the 
square of the diameter by .7854. 
To find the sides of an equal square, mul¬ 
tiply the diameter by .8862. 
To find the capacity of cylindrical tanks, 
square the diameter in inches, multiply by the 
height in inches, and this product by the 
decimal 34. Point off four decimals and you 
have the capacity in gallons. 
To find the contents of a pile of cordwood,
