1. What is the Pressure Washer Nozzle Equation?

The Pressure Washer Nozzle Equation calculates the pressure output based on flow rate and nozzle size. It provides a fundamental relationship between these key parameters in pressure washer systems.

2. How Does the Calculator Work?

The calculator uses the Pressure Washer Nozzle equation:

Where:

• \( Flow \) — Flow rate in gallons per minute (gpm)
• \( Nozzle\ Size \) — Nozzle orifice size
• \( Pressure \) — Resulting pressure in psi

Explanation: The equation demonstrates the inverse relationship between nozzle size and pressure - smaller nozzles produce higher pressure at the same flow rate.

3. Importance of Pressure Calculation

Details: Accurate pressure calculation is crucial for selecting the right nozzle size, optimizing cleaning performance, and ensuring equipment operates within safe pressure limits.

4. Using the Calculator

Tips: Enter flow rate in gpm and nozzle size in orifice units. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is nozzle size important in pressure washers?
A: Nozzle size directly affects the pressure output and cleaning efficiency. Smaller nozzles create higher pressure for tougher cleaning jobs.

Q2: What are typical flow rates for pressure washers?
A: Residential pressure washers typically range from 1.5-2.5 gpm, while commercial units can go up to 5-8 gpm or more.

Q3: How does pressure affect cleaning performance?
A: Higher pressure provides better cleaning power for stubborn dirt and grime, but must be balanced with appropriate flow rate for optimal results.

Q4: Are there safety considerations with nozzle selection?
A: Yes, using nozzles that create excessive pressure can damage surfaces and potentially cause injury. Always follow manufacturer recommendations.

Q5: Can this equation be used for all pressure washer types?
A: This basic equation applies to most pressure washer systems, but specific models may have additional factors to consider.
