The Metric System.

The fundamental unit of the metric system is the meter (the unit of length). From this the units of mass (gram) and capacity (liter) are derived. All other units are the decimal sub-divisions or multiples of these. These three units are simply related, so that for all practical purposes the volume of one kilogram of water (one liter) is equal to one cubic decimeter.

Prefixes. Meaning. Units.

Milli- = one thousandth 1-1000 .001 Meter for length.

Centi- = one hundredth 1-100 .01

Deci- = one tenth 1-10 .1

Unit = one 1. Gram for mass.

Deka- = ten 10-1 10.

Hecto- = one hundred 100-1 100. Liter for capacity.

Kilo- = one thousand 1000-1 1000.

The metric terms are formed by combining the words "Meter," "Gram" and "Liter" with the six numerical prefixes.

Length

10 milli-meters mm = 1 centi-meter c m

10 centi-meters = 1 deci-meter d m

10 deci-meters = 1 meter (about 40 inches) m

10 meters = 1 deka-meter d k m

10 deka-meters = 1 hecto-meter h m

10 hecto-meters = 1 kilo-meter (about 5/8 mile) k m

Mass.

10 milli-grams. m g = 1 centi-gram c g

10 centi-grams = 1 deci-gram d g

10 deci-grams = 1 gram (about 15 grains) g

10 grams = 1 deka-gram d k g

10 Deka-grams = 1 hecto-gram h g

10 hecto-grams = 1 kilo-gram (about 2 pounds) k g

Capacity.

10 milli-liters. m l = 1 centi-liter c l

10 centi-liters = 1 deci-liter d l

10 deci-liters = 1 liter (about 1 quart) l

10 liters = 1 deka-liter d k l

10 deka-liters = 1 hecto-liter (about a barrel) h l

10 hecto-liters = 1 kilo-liter k l

The square and cubic units are the squares and cubes of the linear units.

The ordinary unit of land area is the Hectare (about 2-1/2 acres).

To find diameter of a circle multiply circumference by .31831.

To find circumference of a circle, multiply diameter by 3.1416.

To find area of a circle, multiply square of diameter by .7854.

To find surface of a ball, multiply square of diameter by 3.1416.

To find side of an equal square, multiply diameter by .8862.

To find cubic inches in a ball, multiply cube of diameter by .5236.

Doubling the diameter of a pipe, increases its capacity four times.

One cubic foot of anthracite coal weighs about 53 lbs.

One cubic foot of bituminous coal weighs from 47 to 50 pounds.

A gallon of water (U. S. standard) weighs 8-1/3 pounds and contains 231 cubic inches.

A cubic foot of water contains 7-1/2 gallons, 1728 cubic inches and weighs 62-1/2 pounds.

To find the number of pounds of water a cylindrical tank contains, square the diameter, multiply by .785 and then by the height in feet. This gives the number of cubic feet which multiplied by 62-1/2 gives the capacity in pounds of water. Divide by 7-1/2 and this gives the capacity in gallons.

A horse-power is equivalent to raising 33,000 pounds 1 foot per minute, or 550 pounds 1 foot per second.

The friction of water in pipes is as the square of velocity. The capacity of pipes is as the square of their diameters; thus, doubling the diameter of a pipe increases its capacity four times.

To find the diameter of a pump cylinder to move a given quantity of water per minute (100 feet of piston being the standard of speed), divide the number of gallons by 4, then extract the square root, and the product will be the diameter in inches of the pump cylinder.

To find the horse-power necessary to elevate water to a given height, multiply the weight of the water elevated per minute in pounds by the height in feet, and divide the product by 33,000 (an allowance should be added for water friction, and a further allowance for loss in steam cylinder, say from 20 to 30 per cent).

To compute the capacity of pumping engines, multiply the area of water piston, in inches, by the distance it travels, in inches, in a given time. Deduct 3 per cent for slip and rod displacement. The product divided by 231 gives the number of gallons in time named.

To find the velocity in feet per minute necessary to discharge a given volume of water in a given time, multiply the number of cubic feet of water by 144 and divide the product by the area of the pipe in inches.

To find the area of a required pipe, the volume and velocity of water being given, multiply the number of cubic feet of water by 144 and divide the product by the velocity in feet per minute. The area being found, the diameter can be learned by using any table giving the "area of circles" and finding the nearest area, opposite to which will be found the diameter to correspond.
