The formula for volume of a pipe (or hose) is V =(PI/4) * D2 * L Assuming that each section of hose is the same length, we can find the volume for each diameter hose. V2-inch = (PI/4)*(2 in)2*L = PI*L V1-inch = (PI/4)*(1in)2*L = 0.25PI*L So the ratio of volumes of 2 inch to 1 inch hose is : V2-inch / V1-inch = PI*L / 0.25PI*L = 4:1
All else being equal, a 2-inch hose carries 4 times the volume as a 1-inch hose.
50 feet of 2.5-inch diameter hose has a volume of: 1.7 cubic feet (12.72 liquid gallons)
8.15 gallons
1.03 gallons
The volume of the 3 inch sphere is 33 times bigger = 27 times bigger. 13 : 33 = 1 : 27
A standard fire hose is 50 feet long. A hose this length with a 2-inch radius grants about 4.36 cubic feet. This volume holds 32 gallons of water.
41/2
The larger hose will also have a greater volume and be able to supply a greater volume of air to the tool you are trying to run. A brad nailer doesn't need much air volume (cfm) but a framing nailer or air sander do. Also, larger hose has less pressure drop over a long distance.
i believe the pressure does not change but the volume of water you will be able to use will be less
Volume of a cylinder = (pi) x (radius)2 x (length) Volume of the hose = (pi) x (2 in)2 x (1200 in) = 15,080 cubic inches= 65.28 gallons That's the volume of the hose. We have no way to tell how much water there may be in it.
Area CalculationThe area of the hose section is equal to pi (3.1416) multiplied by the square of the radius. Garden hose comes in a variety of sizes, from 1/2-inch to 1-inch. 3/4-inch hose is typical. Using that as an example, the square of the radius (.375 multiplied by .375) equals .140625. That result multiplied times pi equals .4417875 square inches.Volume CalculationTo calculate the volume, the length of the hose must first be converted to the same measurement standard. 100 feet of garden hose is 1,200 inches. 1,200 times .4417875 equals 530.145 cubic inches.Volume ConversionTo state the volume in a more meaningful manner, cubic inches should be converted to a more common measure of liquid volume. One gallon of water contains 231 cubic inches. So, the 100-foot long, 3/4-inch diameter garden hose holds 2.3 gallons of water (530.145 divided by 231).
The capacity of a 25 ft hose with a diameter of 3 inches is 1.23 cubic feet. That is the maximum volume of water in the hose: there need not be any!
