Poly Pipe Flow Rate Calculator

Flow Rate Formula:

\[ Q = A \times v \]

m/s

1. What is a Poly Pipe Flow Rate Calculator?

Definition: This calculator estimates the volumetric flow rate through a poly pipe based on the cross-sectional area and flow velocity.

Purpose: It helps plumbers, irrigation specialists, and engineers determine the water flow capacity of poly pipes.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Q = A \times v \]

Where:

  • \( Q \) — Flow rate (cubic meters per second, m³/s)
  • \( A \) — Cross-sectional area (square meters, m²)
  • \( v \) — Flow velocity (meters per second, m/s)

Explanation: The flow rate is calculated by multiplying the pipe's internal cross-sectional area by the average velocity of the fluid.

3. Importance of Flow Rate Calculation

Details: Accurate flow rate calculation ensures proper pipe sizing, efficient system design, and prevents issues like excessive pressure loss or inadequate flow.

4. Using the Calculator

Tips:

  • For circular pipes: Area = π × (diameter/2)²
  • Typical velocity ranges: 0.5-2.5 m/s for water in poly pipes
  • All values must be > 0

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate area for a circular poly pipe?
A: Use the formula A = π × r² where r is the internal radius in meters.

Q2: What's a typical flow velocity for water in poly pipes?
A: Generally 0.5-2.5 m/s, with 1-1.5 m/s being most common for efficient operation.

Q3: Does pipe diameter affect flow rate?
A: Yes, significantly! Flow rate increases with the square of the pipe radius.

Q4: How does pipe length affect the calculation?
A: Pipe length affects pressure drop but not the basic flow rate calculation shown here.

Q5: Can I use this for other fluids besides water?
A: Yes, but the velocity range may differ based on fluid viscosity and density.
