How This Is Calculated


$$Q = vA = \frac{V}{t}$$ where:

Q   =   Flowrate   (m³/s)

v   =   Velocity   (m/s)

A1   =   Cross-sectional area 1   (m²)

V   =   Volume of fluid   (m³)

t   =   Time   (s)


Assumptions


  • The fluid is incompressible and Newtonian.
  • The fluid is in a steady flow.
  • The flow ideal.
  • There are negligible external forces.
  • There are no energy losses.
