## Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1914 edition. Excerpt: ...of cubic feet of water by 144, and divide the product by the area of the pipe in inches. AREA OF CIRCLES AND THEIR CIRCUMFERENCE. To find the circumference of a circle: multiply the diameter by 3.1416 and the product will be the circumference. To find the area of the body of a cylinder: multiply the diameter by 3.1416 and this sum by the length, and divide by 144; the quotient will be the area in square feet. Example: a cylinder 36x36 inches; 36x3.1416x36_--407l.5l36+i44:28.1355 square feet. To find the area of any piston or other circle, square the diameter and multiply by.7854. The circumference of a circle multiplied by 0.282 equals side of a square of same area. Useful in turning round tanks into square. To find contents in gallons of a square vessel: multiply number of cylindrical inches by.0034 for wine gallons, by.002785 for ale gallons. To find the capacity of a four-sided vessel in gallons; find cubical contents by multiplying the length, breadth, and height in inches, and divide product by Z31. To find contents in gallons of a vessel whose diameter is larger at one end than the other: multiply the larger diameter by the smaller iii inches; add one-third of the square of their difference; multiply that sum my the height, and multiply that product by.0034 for wine, or.002785 for ale gallons. Sphere or ball: To find cubic contents of: multiply the cube of the diameter by.5623. To find the surface of a sphere: multiply the circumference by the diameter. In CALCULATING HORSEPOWER of steam boilers, consider: Tubler boilers, 15 square feet of heating surface, cquivalent to 1 horsepower. Portable boilers, 12 square feet of heating surface, equivalent to 1 horsepower. Cylinder boilers, 10 square feet of heating surface, equivalent to 1...show more
