Enter Flow Rate :		m3/s
Enter Cross-Sectional Area :		m2
Result – Velocity :		m/s

Flow to Velocity Formula:

Velocity in a channel or pipe is determined by the flow rate of the fluid and the cross-sectional area of the channel or pipe through which it flows.

Flow to velocity, V_(m/s) in metres per seconds is calculated by dividing the flow rate, Q_(m3/s) in cubic metres per second by cross-sectional area, A_(m2) in square metres.

Flow to velocity, V_(m/s) = Q_(m3/s) / A_(m2)

V_(m/s) = velocity in metres per seconds, m/s.

Q_(m3/s) = flow rate in cubic metres per seconds, m³/s.

A_(m2) = cross-sectional area in square metres, m².

Flow to Velocity Calculation:

1.A water pipe with a flow rate of 0.5 m³/s and a cross-sectional area of 0.1 m².

Given:             Q_(m3/s) = 0.5m³/s, A_(m2) = 0.1m².

Flow to velocity, V_(m/s) = Q_(m3/s) / A_(m2)

V_(m/s) = 0.5 / 0.1

V_(m/s) =5m/s.

2.Suppose a canal has a flow rate of 120m³/s and the water is moving with a velocity of 3m/s. Calculate the cross-sectional area of the canal.

Given:             Q_(m3/s) = 120m³/s, V_(m/s) =3m/s.

Flow to velocity, V_(m/s) = Q_(m3/s) / A_(m2)

A_(m2) = Q_(m3/s) / V_(m/s)

A_(m2) = 120 / 3

A_(m2) = 40m².
