1. What is the Nozzle Equation?

The nozzle equation calculates the nozzle size based on flow rate (gpm), a constant factor, and pressure (psi). It helps determine the appropriate nozzle size for pressure washers to achieve optimal cleaning performance.

2. How Does the Calculator Work?

The calculator uses the nozzle equation:

Where:

• \( gpm \) — Flow rate in gallons per minute
• \( constant \) — Unitless constant factor
• \( psi \) — Pressure in pounds per square inch

Explanation: The equation accounts for the relationship between flow rate, pressure, and nozzle size to determine optimal performance.

3. Importance of Nozzle Calculation

Details: Proper nozzle sizing is crucial for achieving the right pressure and flow rate combination for effective cleaning while preventing damage to surfaces or equipment.

4. Using the Calculator

Tips: Enter flow rate in gpm, the appropriate constant for your system, and pressure in psi. All values must be valid (greater than 0).

5. Frequently Asked Questions (FAQ)

Q1: What is a typical constant value?
A: The constant varies by manufacturer and nozzle type, typically ranging from 1000 to 5000.

Q2: How does nozzle size affect cleaning?
A: Smaller nozzles increase pressure but decrease flow rate, while larger nozzles decrease pressure but increase flow rate.

Q3: What's the relationship between gpm and psi?
A: Higher gpm requires more water flow, while higher psi provides more cleaning power. The nozzle balances these factors.

Q4: Are there limitations to this equation?
A: This provides a general calculation. Actual performance may vary based on nozzle design, water temperature, and system efficiency.

Q5: Should I round the nozzle size?
A: Yes, nozzle sizes are typically available in standard increments, so round to the nearest available size.
