Velocity using Water Flow Equation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Flow Velocity = Water Flow/Cross-Sectional Area
V_f = Q/A_cs
This formula uses 3 Variables

Variables Used

Flow Velocity - (Measured in Meter per Second) - Flow Velocity is the velocity of the flow of any fluid.
Water Flow - (Measured in Cubic Meter per Second) - Water Flow is rate of flow of water.
Cross-Sectional Area - (Measured in Square Meter) - Cross-Sectional Area is the area of a two-dimensional shape that is obtained when a three-dimensional shape is sliced perpendicular to some specified axis at a point.

STEP 1: Convert Input(s) to Base Unit
