1. What is the Nozzle Size Equation?

The Nozzle Size Equation calculates the appropriate nozzle size for a pressure washer based on flow rate and a gallons factor. This helps optimize cleaning performance and water usage.

2. How Does the Calculator Work?

The calculator uses the nozzle size equation:

Where:

• \( size \) — Nozzle size (unitless)
• \( gallons\_factor \) — Gallons factor (unitless)
• \( flow\_rate \) — Flow rate in gallons per minute (gpm)

Explanation: The equation provides a simple way to determine the optimal nozzle size based on your pressure washer's flow rate and a specific gallons factor.

3. Importance of Nozzle Size Calculation

Details: Proper nozzle sizing ensures optimal cleaning performance, prevents damage to surfaces, and maximizes water efficiency. An incorrectly sized nozzle can lead to poor cleaning results or surface damage.

4. Using the Calculator

Tips: Enter flow rate in gpm and the appropriate gallons factor for your application. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I determine the gallons factor?
A: The gallons factor depends on your specific pressure washer model and the desired pressure. Consult your manufacturer's specifications.

Q2: What is a typical flow rate for pressure washers?
A: Residential pressure washers typically have flow rates between 1.5-2.5 gpm, while commercial units may go up to 5 gpm or more.

Q3: How does nozzle size affect pressure?
A: Smaller nozzle sizes increase pressure while reducing flow rate, and vice versa. The right balance is crucial for effective cleaning.

Q4: Can I use this calculator for any pressure washer?
A: Yes, as long as you have the correct gallons factor for your specific machine and application.

Q5: Why is my calculated nozzle size not available commercially?
A: Nozzle sizes come in standard increments. Choose the closest available size to your calculated value.
