  4. Hazen–Williams equation - Wikipedia

    en.wikipedia.org/wiki/Hazen–Williams_equation

    The Hazen–Williams equation is an empirical relationship that relates the flow of water in a pipe with the physical properties of the pipe and the pressure drop caused by friction. It is used in the design of water pipe systems [ 1 ] such as fire sprinkler systems , [ 2 ] water supply networks , and irrigation systems.

    The bends are of cast-iron tested to 1,700 kPa (250 psi). There are no expansion joints; the pipes are kept full of water and are buried underground so that the temperature variation is small. The pipe line is connected to a 0.91-metre-diameter (36 in) steel receiver pipe, 8.2 m long (27 ft), made of 9.5 mm-thick (3 ⁄ 8 in) plate steel. It is ...

    EG: Propane will convert from a gas to a liquid under light pressure, 100 psi, give or take depending on temperature, and is pumped into cars and trucks at less than 125 psi (860 kPa) at retail stations. Pipelines and rail cars use about double that pressure to pump at 250 psi (1,700 kPa). An elevated section of the Trans-Alaska Pipeline System

    The number system, like Sch 40, 80, 160, were set long ago and seem a little odd. For example, Sch 20 pipe is even thinner than Sch 40, but same OD. And while these pipes are based on old steel pipe sizes, there is other pipe, like cpvc for heated water, that uses pipe sizes, inside and out, based on old copper pipe size standards instead of steel.
