Pipe diameter and flow rate

WebbA characteristic quantity describing the viscous flow state is the dimensionless Reynolds number Re. Re is the product of the pipe diameter, flow velocity, density and reciprocal value of the viscosity (internal friction) of the gas which is flowing. Flow is turbulent where Re > 2200, laminar where Re < 2200.

Plumbing size The diameter of plumbing pipes limits the flow of water depending on their size. The larger the pipe's diameter, the greater the water flow. For instance, the flow rate of 3/4

Webb2 nov. 2024 Β· For example, if your pipe's minimum ID at restrictions is 18mm, the flow rate would be two-thirds of a 22mm pipe. Actually, for a given head the flow through a pipe is - all other things being equal - proportional to the diameter to the power 2.5, so an 18mm pipe would carry about 60% as much as a 22mm pipe. Not that far off two-thirds, though.
