the amount required to fill the line = (Π/4)*D^2*L where D is the inside dia of the pipeline & L is the length, in your case this amounts to 2281.101 m3 of water.
Use water for testing.
The volume of water displaced is equal to the volume of the object submerged into the water
To calculate the volume of water displaced by an anchor on the ocean floor, you can use Archimedes' principle. The volume of water displaced will be equal to the volume of the anchor that is submerged underwater. By knowing the density of water and the weight of the anchor, you can calculate the volume of water displaced.
The equation to calculate water depth is: [ Water Depth = Volume of Water / Surface Area of Water ]
To calculate the water difference when the density changes, you would need to account for the change in volume due to the density change. Use the formula: Difference in water volume = Original water volume / Original water density - Original water volume / New water density. Multiply this difference in volume by the new water density to obtain the actual water difference.
The easy way: Pour the water into a graduated container, like a graduated cylinder, and read the volume directly. The hard way: Calculate the volume of a regularly shaped container (cylindrical or rectangular). Pour the water into the container. Measure the height of the water in the container. Calculate the volume of the unfilled portion of the container. Subtract this volume from the total volume of the container.
you subtract the weight of the water from the weight of the measuring cylinder and you get the volume of the stone
water displacement
Water displacement
Volume of water = (pi) x (Radius of the well)2 x (depth of the water)
Use a measured water cylinder, drop in the object, the amount of water displaced represents the volume of the object
