Flow rate $Q$, fluid velocity $V$ or flow area $A$ calculator

Volumetric Flow Rate Calculator

Solve for Flow Rate ($Q$), Velocity ($V$), or Pipe Area ($A$)

Governing Formulas:
$$Q = V \cdot A$$ $$A = \frac{\pi \cdot D^2}{4}$$

Select Target Variable to Solve For: Flow Rate (Q) Fluid Velocity (V) Flow Area (A) / Diameter (D)

Flow Rate, $Q$ ($\text{m}^3/\text{s}$):

Fluid Velocity, $V$ ($\text{m}/\text{s}$):

Pipe Inner Diameter, $D$ ($\text{m}$):
