While pipe sizes in Australia are inch-based, they are classified by outside rather than inside diameter (e.g., a nominal 3 ⁄ 4 inch copper pipe in Australia has measured diameters of 0.750 inches outside and 0.638 inches inside, whereas a nominal 3 ⁄ 4 inch copper pipe in the U.S. and Canada has measured diameters of 0.875 inch outside and ...
The difference between pipes and tubes is a matter of sizing. For instance, PVC pipe for plumbing applications and galvanized steel pipe are measured in iron pipe size (IPS). Copper tube, CPVC, PeX and other tubing is measured nominally, basically an average diameter. These sizing schemes allow for universal adaptation of transitional fittings.
Fittings allow multiple pipes to be connected to cover longer distances, increase or decrease the size of the pipe or tube, or extend a network by branching, and make possible more complex systems than could be achieved with only individual pipes. Valves are specialized fittings that permit regulating the flow of fluid within a plumbing system.
Different size meters indicate different resolutions of the reading. One rotation of the sweep hand may be equivalent to 10 gallons or to 1,000 gallons (1 to 100 ft 3, 0.1 to 10 m 3). If one rotation of the hand represents 10 gallons, the meter has a 10-gallon sweep.
The history of copper pipe is similar. In the 1930s, the pipe was designated by its internal diameter and a 1 ⁄ 16-inch (1.6 mm) wall thickness. Consequently, a 1-inch (25 mm) copper pipe had a 1 + 1 ⁄ 8-inch (28.58 mm) outside diameter. The outside diameter was the important dimension for mating with fittings.
Mathematically the flow coefficient C v (or flow-capacity rating of valve) can be expressed as =, where Q is the rate of flow (expressed in US gallons per minute), SG is the specific gravity of the fluid (for water = 1), ΔP is the pressure drop across the valve (expressed in psi).
