1. What is the Nozzle Size Equation?

The nozzle size equation calculates the tool size for pressure washer nozzles based on the relationship between pressure and flow rate. It helps determine the optimal nozzle size for specific cleaning applications.

2. How Does the Calculator Work?

The calculator uses the nozzle size equation:

Where:

• \( Pressure \) — Water pressure in pounds per square inch (psi)
• \( Flow \) — Water flow rate in gallons per minute (gpm)
• \( Tool\ Size \) — Unitless value representing nozzle size

Explanation: The equation shows the direct relationship between pressure and flow rate in determining nozzle size.

3. Importance of Nozzle Size Calculation

Details: Proper nozzle sizing is crucial for achieving optimal cleaning performance, water efficiency, and equipment longevity in pressure washing applications.

4. Using the Calculator

Tips: Enter pressure in psi and flow rate in gpm. Both values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is nozzle size important?
A: Nozzle size affects cleaning power, water consumption, and surface impact. Proper sizing ensures efficient operation without damaging surfaces.

Q2: What are typical pressure washer specifications?
A: Residential units typically operate at 1,500-3,000 psi with 1.5-2.5 gpm, while commercial units may reach 3,000-4,000 psi with 3-5 gpm.

Q3: How does nozzle size affect pressure?
A: Smaller nozzles increase pressure but reduce flow rate, while larger nozzles decrease pressure but increase flow rate.

Q4: Are there limitations to this equation?
A: This provides a basic calculation. Actual nozzle selection should also consider spray pattern, distance, and surface type.

Q5: Should I consult a professional for nozzle selection?
A: For critical applications or expensive equipment, professional consultation is recommended to ensure optimal performance and safety.
