where \( Re \) is the Reynolds number. However, as the flow transitions to a turbulent regime, the calculation becomes more complex. The turbulent flow friction factor is determined using empirical correlations, such as the Colebrook-White equation, which accounts for both the Reynolds number and the relative roughness of the pipe.

1. PSI and GPM Ratings Look for models with a PSI (pounds per square inch) rating between 1200-2000 for safe and effective car washing. A higher PSI might be too aggressive and could damage the paint. The GPM (gallons per minute) indicates how much water the unit can deliver; a higher GPM leads to better cleaning efficiency.
