Volumetric Flow Rate vs Pipe Inner Diameter

Vedi formula →

Formula

## Volumetric & Mass Flow Rate Flow rate through a pipe depends on the cross-sectional area and the average fluid velocity. ### Formulas **Q = A V = (pi D^2 / 4) V** (volumetric flow) **m_dot = rho Q = rho A V** (mass flow) where D is the pipe diameter, V is the average velocity, and rho is the fluid density.

Esempio Risolto

Water flowing at 2 m/s through a 100 mm diameter pipe.

  1. 01D = 100 mm = 0.1 m
  2. 02A = pi x 0.1^2 / 4 = 0.007854 m^2
  3. 03Q = 0.007854 x 2 = 0.01571 m^3/s = 15.71 L/s
  4. 04Mass flow = 1000 x 0.01571 = 15.71 kg/s
