Water Flow Formula:
From: | To: |
Definition: This calculator estimates the volumetric flow rate of water through a pipe based on the pipe's radius and water velocity.
Purpose: It helps engineers, plumbers, and fluid system designers determine water flow rates for piping systems.
The calculator uses the formula:
Where:
Explanation: The formula calculates the cross-sectional area of the pipe (πr²) and multiplies it by the water velocity to determine volume per second.
Details: Accurate flow rate calculations ensure proper pipe sizing, efficient system design, and prevent issues like excessive pressure loss or inadequate flow.
Tips: Enter the pipe radius in meters and water velocity in meters per second. All values must be > 0.
Q1: Can I use diameter instead of radius?
A: Yes, simply divide the diameter by 2 before entering it as the radius.
Q2: What's a typical water velocity in pipes?
A: Domestic water systems typically range 0.5-2.5 m/s, with 1-1.5 m/s being common for optimal balance.
Q3: How do I convert m³/s to liters/second?
A: Multiply the result by 1000 (1 m³/s = 1000 L/s).
Q4: Does this work for other liquids?
A: Yes, the formula works for any incompressible fluid, though viscosity effects are not considered.
Q5: How does pipe roughness affect the calculation?
A: Pipe roughness affects velocity (via pressure loss) but not this direct calculation. Use Bernoulli's equation for more complex scenarios.
