The volume of water that a length of 3/4 inch pipe can hold depends on its length. The internal diameter of a 3/4 inch pipe is approximately 0.824 inches. To calculate the volume, you can use the formula for the volume of a cylinder: V = πr²h, where r is the radius (0.412 inches) and h is the length of the pipe in inches. For example, a 10-foot length (120 inches) of 3/4 inch pipe holds about 0.61 gallons of water.
To determine how much water a 6-inch pipe can hold, you need to calculate its volume based on its length. The volume (in gallons) can be found using the formula for the volume of a cylinder: ( V = \pi r^2 h ), where ( r ) is the radius (3 inches for a 6-inch pipe) and ( h ) is the length of the pipe in inches. For example, a 10-foot (120-inch) length of a 6-inch pipe would hold about 18.9 gallons of water.
To calculate the weight of a 30-foot piece of 3-inch diameter aluminum pipe, you first need to determine the volume of the pipe and then multiply it by the density of aluminum, which is approximately 0.0975 pounds per cubic inch. The volume of the pipe can be calculated using the formula for the volume of a cylinder: ( V = \pi r^2 h ), where ( r ) is the radius and ( h ) is the height (or length of the pipe). A 3-inch diameter pipe has a radius of 1.5 inches, so the volume is roughly 211.3 cubic inches, resulting in a weight of about 20.6 pounds for a 30-foot length.
To determine if the flow is laminar or turbulent, we can calculate the Reynolds number (Re). For a 3-inch diameter GI pipe and a flow velocity of 2 meters per second, the Reynolds number is likely to be greater than 4000, indicating turbulent flow. In general, flow is considered laminar if Re is less than 2000 and turbulent if Re exceeds 4000. Given these conditions, the flow is turbulent.
To calculate the amount of concrete needed to fill a 50-foot long, 6-inch diameter pipe, first determine the volume of the pipe. The formula for the volume of a cylinder is ( V = \pi r^2 h ), where ( r ) is the radius and ( h ) is the height (or length). The radius of a 6-inch pipe is 3 inches (0.25 feet), so the volume is approximately ( V = \pi (0.25^2)(50) ), which equals about 9.82 cubic feet. Thus, you would need approximately 9.82 cubic feet of concrete to fill the pipe.
The volume of a 3-inch pipe that is 1,000 feet long is: 49.09 cubic feet.
The volume of one foot of 3-inch PVC pipe is: 84.82 cubic inches. In terms of liquid, this equates to about 0.3672 (US) gallons or 47 fluid ounces for that section of pipe.

3 inch (inside diameter) pipe = 0.25 feet. Radius = 0.125 ft Cross section area = pi*(0.125 ft)2 = pi * 0.015625 ft2 . Multiply by 80 ft = pi * 1.25 cubic feet = 3.926990817 cubic feet x 7.480517578 (US gallons / cubic ft) = 29.37592384 US gallons.
what is the discharge flow of 10m/s passing from 2ft pipe
That's 3/4" pipe, not 3.4" prehaps it would deliver more pressure through the 1/2 inch pipe than 3/4 inch. 3/4" pipe will be less restrictive over the course of the run. Otherwise, no. 1/2" Copper Pipe will do fine, since it has a smoother bore, less restrictive, no lime and rust build-up. The only reason for you to use 3/4" pipe is if you want more volume. The pressure remains the same.
In order to effectively answer this question more factors would need to be known. The most important factor being the type of liquid flowing through the pipe. Different liquids have a different rate of flow, even with varying elevations.
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.

The size of sprinkler pipe you should use for your irrigation system depends on the water flow and pressure needed. Generally, a 1-inch pipe is recommended for larger systems or areas with high water demand, while a 3/4-inch pipe is suitable for smaller systems or areas with lower water demand. It is important to consider factors such as water pressure, flow rate, and the number of sprinkler heads when choosing the pipe size for your irrigation system.
