Flow Rate Formula:
From: | To: |
Definition: This calculator determines the volumetric flow rate of water through a pipe based on the pipe's cross-sectional area and the water velocity.
Purpose: It helps engineers, plumbers, and irrigation specialists design and analyze water distribution systems.
The calculator uses the fundamental flow rate equation:
Where:
Explanation: The flow rate equals the pipe area multiplied by the average velocity of the water.
Details: Accurate flow rate calculations ensure proper pipe sizing, adequate water supply, and efficient system design while preventing pressure drops or pipe damage.
Tips:
Q1: How do I calculate pipe area?
A: For circular pipes: A = πr² where r is the radius. Convert diameter to radius by dividing by 2.
Q2: What's a typical water velocity in pipes?
A: Domestic systems: 0.5-1.5 m/s, Industrial systems: 1.5-3 m/s.
Q3: Can I use this for other liquids?
A: Yes, as long as you have the correct velocity measurement for that liquid.
Q4: How does pipe material affect flow rate?
A: Material affects friction loss but not this basic calculation. For precise work, consider the Hazen-Williams equation.
Q5: What if my pipe isn't circular?
A: Use the appropriate area formula (e.g., for rectangular pipes: A = width × height).
