Surface Cleaner Nozzle Calculator

Use this calculator to estimate the Output PSI based on factors including: your pressure washers GPM and PSI, the number of nozzles and nozzle sizes in your surface cleaner, and the length of hose you are using.

Fill out all of the fields and adjust the nozzle size option to calculate the output PSI of your choosing. (Make sure to click out of the calculator, or hit Enter/Return, after entering the hose length to perform the final calculation)

Please note, the output PSI is approximate as there are other contributing factors to pressure that slightly affect the total, such as additional angled plumbing pieces etc.
