There need not be any water at all in the hose! The capacity of the hose is 1.67 cubic feet.
8.15 gallons
It is an accepted fire service understanding that 5" Large Diameter Hose (LDH) will hold 1 gallon/ft. On average a 100' section of 5" empty weighs 110 lbs. With water weighing 8.33 lbs/gal. a 100' section of LDH filled with water will weigh approximately 944 lbs.
volume = pir2h pi = 3.1416 h = 100 feet r = 1/2 X diameter r = 1/2 X 3/4 inch / 12 inches/ft = 0.03125 square feet volume = 3.1416 X (0.03125)2 X 100 = 0.3 cubic feet
100 As 12 inch = 1 foot 10 x 10 = 100 100 / 1 = 100

A 100-foot hose with an inside diameter of five inches can hold 102 US gallons of water.

Assuming the hose has an inner diameter of 1 inch, 100 feet of 3" hose filled with water would weigh approximately 6,242 pounds.
There need not be any water at all in the hose! The capacity of the hose is 3.41 cubic feet.
That section of hose holds 25.5 gallons of water when it's full, which weighs about 213 pounds. To that, add the weight of the empty hose, which I don't know.
Around 943 lbs. Water weighs 8.33 lbs/gal. 5 inch hose holds 1 gal per 1 foot of hose. So 8.33x100 foot is 833 lbs. Add that to the 110 lbs that the hose weighs empty and you have 943 lbs
100 pounds with couplings, 68 without.
The weight of rubber hose varies depending on the density of the rubber material. On average, a 4-inch rubber hose weighs about 0.15-0.2 pounds per foot. So, 100 feet of 4-inch rubber hose would weigh approximately 15-20 pounds.
A 2.5 inch fire hose has a capacity of approximately 60 gallons per 100 ft. Therefore, a 50 ft hose would hold around 30 gallons of water.
V = pi*r2*h = pi*(1.5/2)2*(100*12) cubic inches = 2120.6 cubic inches.
