Page 279 - To find the pressure in pounds per square inch of a column of water, multiply the height of the column in feet by .434. Approximately we say that every foot elevation is equal to % pound pressure per square inch; this allows for ordinary friction. To find the diameter of a pump cylinder...

Page 279 - 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 quantity of water elevated in one minute...

Page 279 - Capacity of a five-inch cylinder is desired; the square of the diameter (5 inches) is 25, which, multiplied by 4, gives 100, which is gallons per minute (approximately). To find the diameter of a pump cylinder to...

Page 6 - A horse-power being the power required to lift 33,000 pounds one foot in one minute...

Page 279 - The mean pressure of the atmosphere is usually estimated at 14.7 pounds per square inch, so that with a perfect vacuum it will sustain a column of mercury 29.9 inches or a column of water 33.9 feet high at sea level. To find the pressure in pounds per square inch of a column of water, multiply the height of the column in feet by .434.

Page 279 - The area of the steam piston, multiplied by the steam pressure, gives the total amount of pressure that can be exerted. The area of the water piston, multiplied by the pressure of water per square inch, gives the resistance. A margin must be made between, the power and the resistance to move the piston at the required speed — say from 20 to 40 per cent., according to speed and other conditions.

Page 279 - To find the capacity of a cylinder in gallons. Multiplying the area in inches by the length of stroke in inches will give the total number of cubic inches ; divide this...

Page 279 - To find quantity of water elevated in one minute running at 100 feet of piston speed per minute. Square the diameter of the water cylinder in inches and multiply by 4. Example: capacity of a 5 inch cylinder is desired.

Page 279 - ... by the height in feet and divide the product by 33,000 (an allowance of 25 per cent, should be added for water friction, and a further allowance of 25 per cent, for loss in steam cylinder).

Page 191 - ... greater elevation and distance is correspondingly strengthened. The relative height of the spring or source of supply above the ram, and the elevation to which it is required to raise, determine the relative proportion between the water raised and wasted, the quantity raised varying according to the height it is conveyed with a given fall; also, the distance the water has to be conducted, and consequent length of pipes, have some influence on the quantity delivered at the point of discharge,...
