1. What is the K-factor?

The K-factor is a proportionality constant that relates the flow rate through a flow nozzle to the square root of the pressure drop across the nozzle. It's commonly used in fluid dynamics and flow measurement applications.

2. How Does the Calculator Work?

The calculator uses the K-factor equation:

Where:

• \( K \) — K-factor (gpm/psi^0.5)
• \( C_d \) — Discharge coefficient (dimensionless)
• \( d \) — Orifice diameter (inches)
• \( D \) — Pipe diameter (inches)

Explanation: The equation accounts for the geometric properties of the flow nozzle and pipe system to determine the flow characteristics.

3. Importance of K-factor Calculation

Details: Accurate K-factor calculation is crucial for proper flow measurement, system design, and performance prediction in fluid systems.

4. Using the Calculator

Tips: Enter the discharge coefficient (typically 0.6-0.99 for flow nozzles), orifice diameter, and pipe diameter in inches. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical discharge coefficient value?
A: For well-designed flow nozzles, C_d typically ranges from 0.95 to 0.99.

Q2: What units does this equation use?
A: The equation uses inches for diameters and outputs K-factor in gpm/psi^0.5.

Q3: Can this be used for any fluid?
A: This specific equation is calibrated for water. For other fluids, additional corrections may be needed.

Q4: What's the relationship between K-factor and flow rate?
A: Flow rate \( Q = K \times \sqrt{\Delta P} \), where \( \Delta P \) is the pressure drop across the nozzle.

Q5: How does pipe diameter affect K-factor?
A: Larger pipe diameter (D) decreases the K-factor, as the denominator in the equation increases.
