Seite 219 - ... of importance and should be considered for each case. The ropes commonly used for the transmission of power in factories or mills vary from 3 to 5 inches in circumference. No matter what the diameter of the pulley may be, ropes of 1| inches diameter should not be exceeded for main drives, and l| inches diameter for secondary drives.
Seite 383 - 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.
Seite 47 - It shall leave by weight a residue of not more than 8 per cent, on the No. 100, and not more than 25 per cent, on the No. 200 sieve.
Seite 385 - To find the head which will produce a given velocity of water through a pipe of a given diameter and length: Multiply the square of the velocity, expressed in feet per second, by the length of pipe multiplied by the quotient obtained by dividing 13.9 by the diameter of the pipe in inches, and divide the result obtained by 2,500. The final amount will give the head in feet. Example.— The horizontal length of pipe is 1,200 feet, and the diameter is 4 inches.
