Microtubing or spaghetti tubing is a very fine plastic tubing used in drip irrigation, typically in gardens and greenhouses, with a small inside diameter which may be 0.05" or smaller. [ 1 ] It was introduced in the 1950s in the United States, in Watertown, New York .
An emitting pipe is a type of drip irrigation tubing with emitters pre-installed at the factory with specific distance and flow per hour as per crop distance. An emitter restricts water flow passage through it, thus creating head loss required (to the extent of atmospheric pressure) to emit water in the form of droplets.
A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.
A pipe support or pipe hanger is a designed element that transfer the load from a pipe to the supporting structures. The load includes the weight of the pipe proper, the content that the pipe carries, all the pipe fittings attached to pipe, and the pipe covering such as insulation. The four main functions of a pipe support are to anchor, guide ...
The irrigation system that provides the most control over water management, though conversely the most expensive to install, is drip irrigation.

Subirrigation also known as seepage irrigation, is a method of irrigation where water is delivered to the plant root zone. The excess may be collected for reuse. The excess may be collected for reuse.
For example, DN20 is the size for copper pipe with an outside diameter of 19.05 mm or 3 ⁄ 4 inch. 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 ...
