Step-by-step solution
Q = A · v
What Is Flow Rate?
Flow rate is the volume of liquid or gas passing through a cross-section per unit of time. It is used in pipe, channel and pump calculations.
How is it calculated?
How Is It Calculated?
Q = V ÷ t = A × v
V: volume, A: cross-sectional area, v: flow velocity.
- Enter the volume and time (or the area and velocity).
Frequently Asked Questions
What happens when the pipe narrows?
If the flow rate is constant, the flow velocity increases as the cross-section narrows (continuity principle).
