How many gallons of water in a half inch diameter hose fifty feet long?

Answer 1

Do you mean a fixed length of 5 inch pipe or are you asking to the amount of laminar flow through a 5 inch pipe? There is not enough info here to answer.

Need length of pipe and what you are asking.

Answer 2

Approximately 0.425 gallons

First find the volume of the hose. We need to make sure the dimensions are in the same units. [I will choose inches, but we could just as easily use feet.] The length of the hose in inches is 50*12=600 inches. The radius of the hose equals one half the diameter, so the radius is 1/4 of an inch. The volume of a cylindrical prism is given by:

pi*radius2*length=pi*(1/4)2*600=125*pi/4 cubic inches, or approximately 98.2 cubic inches.

One cubic inch is approximately .00433 gallons, so:

98.2 cubic inches = 98.2 cubic inches*.00433 gallons/cubic inch=0.425 gallons

So there are approximately 0.425 gallons of water in the hose.
