volume = pi r squared multiplied by the length you didnt specify wether 2 inch pipe was diameter or radius
If the flow velocity remains the same the flow volume will increase by the square of the diameter ratio.(2/1.25) = 1.6 = diameter ratio1.62 = 2.56 more flow volume through 2 inch pipe compared to 1.25 inch pipe.
Volume of the pipe = 4.896 gallons
Assuming that 0.75 inch refers to the diameter, the volume is pi*(0.75/2)2*12 = 5.3 cubic inches, approx.
It is based on the flow area, which is proportional to the square of the diameter. 2 squared = 4. 4 squared = 16. So, the 4 inch pipe can take 16/4 = 4 times the volume of the 2 inch pipe. It might be less confusing if you had picked sizes other than 2 and 4. This is a rough calculation, since pipe inside diameters are not the same as nominal sizes, but close enough for most purposes.
Just search for the numerous questions about the volume of a cylinder. Note that a 2-in pipe has a radius of one inch.
You would need to know the length of the pipe in order to answer the question. The equation for volume of a cylinder is V=πr2h. For example, for one foot of 2" pipe, you would multiply 3.14 by 2" by 12" and find you have 37.7 cubic inches of volume inside the pipe.
The answer will depend on whether it is a 2 inch pipe or a 2 cm pipe or a 2 foot pipe or whatever.The answer will depend on whether it is a 2 inch pipe or a 2 cm pipe or a 2 foot pipe or whatever.The answer will depend on whether it is a 2 inch pipe or a 2 cm pipe or a 2 foot pipe or whatever.The answer will depend on whether it is a 2 inch pipe or a 2 cm pipe or a 2 foot pipe or whatever.
The volume is 0.7418 cubic feet OR 1,281.8 cubic inches. This pipe would contain 5.549 gallons of water.
The pipe's volume is the product of its cross-sectional area and its length. The area of a circle is pi*(radius)^2, so in this case pi*9sq.in. or about 28.3 square inches. Multiply this area by the length of pipe you are using to obtain a volume. A 10 foot length of 6 inch pipe will have 3393 cubic inches of volume or 1.96 cubic feet, or 14.7 US Gallons.
A pipe with an inside diameter of 2 inches has 37.7 cubic inches (rounded) of interior volume per foot. That means about 6feet 1.5inches per gallon.
Volume = 0.8727 cubic feet OR 1,508 cubic inches.
The pipe is a cylinder.Volume of a cylinder = (pi) x (Radius)2 x (length)Radius = 1/2 diameterVolume of the pipe = (pi) x (1)2 x 120 = 120 pi = 377 cubic inches = 1.632 gallons.That's the volume of the pipe. I have no way to know if there's anything in it.
