Fluid Flow Rate Calculator

Calculate the flow rate of a fluid in a pipe using the continuity equation.

Flow Rate Calculation

Enter the fluid velocity and pipe diameter to calculate the flow rate.

Formula Used:

Q = A × V

Where:

  • Q = Flow rate (m³/s)
  • A = Cross-sectional area of the pipe (m²) = π × (D/2)²
  • V = Fluid velocity (m/s)
