This pipe has a volume of 24.5 cubic feet.
1) pi x 36 square inches = area of a cross section of a 12 inch (round) pipe (the radius is 6 inches). 2) There are 144 square inches in a square foot (1 ft x 1 ft = 12 in. x 12 in. = 144 square inches) So, the area of a cross section of a 12 inch pipe is (pi x 36)/144 = pi/4 square feet.
48First of all, you must have meant cubic feet (volume) not square feet.The area of a 2 ft. diameter pipe is 2*2*Pi/4 = Pi = 3.1416 sq.ft.The volume = area*length = 3.1416*12 = 37.6991cu.ft."Diameter" implies a round pipe.

Seven miles of pipe equates to 36,960 feet
8 inch schedule 40 pipe has a cross sectional area of 0.0583 square feet
A measure of the length will be in linear units. So make sure that the measurement is made or expressed in metres.
The external surface area of a pipe is a rectangle with dimensions of the circumference of the pipe multiplied by the length. 48*pi*500 24000*pi square feet about 7550208 square feet
1000 inches = 83.3 feet = 27.8 yards
10 feet X 4" round x 10 feet =
Convert all units to feet, and use the formula for a cylinder - pi x radius square x height (the height is the length in this case).
A pipe is a cylinder.Diameter = 6 inches = 0.5 feet=> Radius = 0.25 feetHeight = 20 feetVolume of a cylinder = pi * r^2 * h square units= 3.1415 * 0.25 * 0.25 * 20 square feet= 3.926875 square feet
You need the pipe cross sectional area (csa) in square feet. Example: Flow = 100 cu ft / min csa pipe = 3.1416 sq ft ( 2 ft dia pipe internal) calculate the length of a cylinder of volume 100 cu ft if vol = csa * length then : length = vol / csa = 100 / 3.1416 = 31.83 feet gas velocity = 31.83 ft / min
First convert gallons to a volumetric unit like cubic ft (ft^3) 7.48 gal per ft^3 Then divide the ft^3 quantity by the cross sectional area of the pipe (converted into square feet ft^2) This will leave you with linear units of feet. This number of feet must travel past a point in the pipe in one minute to deliver a gallon. You can then do the time conversion to obtain ft/sec from ft/min. Consider a cylinder with a diameter equal to the pipe inside diameter. How tall would that cylinder have to be in order to hold a gallon of water. Its the same type of problem only with the added twist that the water is flowing past a point in a given amount of time.
To find the surface area of the pipe, we first need to calculate the circumference of the pipe: Circumference = π x Diameter. In this case, the circumference is 3.14 x 12 inches. To convert inches to meters, divide by 39.37. Therefore, the surface area of the pipe would be 10 meters x (3.14 x 12 inches / 39.37).
Use the formula for a cylinder to calculate the volume. This volume will be in cubic feet; you can then convert that to gallons.
