Area & materials
Calculate square metres and estimated material for building, paint and flooring.
WISKUNDE
Relate pipe flow, velocity and diameter; interpret Reynolds and pressure from head.
ZO WERKT HET
Choose one unknown and the tool calculates flow, velocity or diameter for a circular pipe. It includes Reynolds and hydrostatic pressure from a liquid column.
Q = A * v; A = piD? / 4; Re = rho vD / muIndicative SI-unit result. It does not calculate head loss or size an installation: losses depend on length, roughness, fittings and valves.
A 100 mm pipe carrying water at 2 m/s conveys approximately 15.71 L/s.
