  5. Pressure Washer and Jetter Nozzle Calculator (amazingmachinery.com) On the bottom calculator.... Option 1. Add up all your nozzles on the gun, so for a xx03 and a xx02 type in 5 Type the pressure you are getting at the GUN not the pump unless you know for sure you are not getting friction loss. Typically a 3/8 50' hose has zero loss under 5 gpm. This will calculate your total GPM at the gun. Option 2. For a single nozzle Type in a 3 for a xx03 nozzle, 2 for a xx02 nozzle, etc. Then type in your pressure and it will calculat

  7. The image quality is bad on the site, so here's a link to the google doc: https://docs.google.com/spreadsheets/d/1B2lLiCZF_AOcQU6bQEUdo6TPlrz1YcLjM-hY4DW1F9A/edit?usp=sharing
  8. Wetbulb Temperature Chart Pressure Washer Nozzle Charts Water flow rate through nozzle at various pressures (GPM, approximate) Use this chart to figure out your total system nozzle number based on your water pump's flow rate and your desired system pressure. Usually 450-600psi is best for cold conditions and 600-800 psi is optimal for marginal temperatures. You can run at higher pressures to help deal with warm water temps, but more water will be lost to evaporation (small drops). Air flow rate through nozzle at various pressures (CF
