Calculation of Flow, Cross section and Velocity of flowing Waters

The flow Q (unit: m³/s) is the product of flow cross section q (unit: m²) and mean flow velocity v (unit: m/s):

Q = q*v

This Calculator needs numbers in two out of the three text fields. The third value is calculated with a click on the button "Calculate". In case of use of decimal places, please use "." as decimal seperator (e.g.: 9.9)!

Flow cross section (q)   Average flow velocity (v) Flow (Q)
