Flow Velocity Formula:
From: | To: |
Definition: This calculator determines the velocity of fluid flowing through a pipe based on the volumetric flow rate and pipe radius.
Purpose: It helps engineers, plumbers, and fluid system designers understand fluid dynamics in piping systems.
The calculator uses the formula:
Where:
Explanation: The flow rate is divided by the pipe's cross-sectional area (πr²) to determine the average velocity.
Details: Proper velocity calculation ensures efficient system design, prevents erosion, and maintains laminar flow conditions.
Tips: Enter the flow rate in m³/s and pipe radius in meters. Both values must be positive numbers.
Q1: What's a typical flow velocity in pipes?
A: For water systems, 0.5-3 m/s is common, with 1-2 m/s being optimal for most applications.
Q2: Does this work for any pipe shape?
A: This formula is for circular pipes. For other shapes, different area calculations are needed.
Q3: What if I know diameter instead of radius?
A: Simply divide the diameter by 2 to get the radius before entering the value.
Q4: How does viscosity affect the result?
A: This gives average velocity. Actual velocity profiles vary with viscosity (higher near center).
Q5: What units should I use?
A: The calculator uses metric units (m³/s and m). For other units, convert first.
