How many gallons will 5000 feet of 18-inch water pipe hold?

Answer 1

To calculate the volume of water that a 5000-foot length of 18-inch diameter water pipe can hold, first find the volume of a cylinder using the formula ( V = \pi r^2 h ), where ( r ) is the radius and ( h ) is the height (or length). The radius of an 18-inch diameter pipe is 9 inches (or 0.75 feet). Plugging in the values, the volume is approximately 105.4 cubic feet. Since there are about 7.48 gallons in a cubic foot, the total volume is approximately 789 gallons.
