Water Velocity Calculator
Calculate water velocity in pipes based on flow rate and pipe dimensions. Determine flow speed for plumbing, irrigation, and hydraulic systems.
Step 1: Pipe Dimensions
Understanding Pipe Dimensions
Pipe diameter significantly affects flow velocity. Smaller pipes create higher velocity at the same flow rate due to reduced cross-sectional area.
Step 2: Flow Parameters
About Flow Rate
Flow rate is the volume of fluid passing through a pipe per unit time. Higher flow rates generally increase velocity, but pipe size and friction also play critical roles.

Water Velocity Formula
Velocity = Flow Rate / Cross-sectional Area
To calculate water velocity: Divide the volumetric flow rate by the cross-sectional area of the pipe. For circular pipes: Area = π × (Diameter/2)²
Flow Types
Laminar vs Turbulent Flow
Laminar flow (Re < 2000): Smooth, orderly flow with layers sliding past each other. Turbulent flow (Re > 4000): Chaotic flow with mixing and eddies.
