What is the nozzle pressure at the application tip of a power sprayer compared to the pressure gauge reading?

The nozzle pressure at the application tip of a power sprayer is considerably less than the pressure gauge indicates due to several factors related to the design and function of the spraying system. The gauge typically measures the pressure within the spray system, which can be influenced by the resistance created as the liquid travels through the hoses and fittings.

As the liquid exits the nozzle, there are losses associated with factors like friction and turbulence, which reduce the pressure at the nozzle compared to the pressure shown on the gauge. This difference is critical for users to understand as it affects the spray pattern, droplet size, and overall effectiveness of the application. Recognizing the actual pressure at the nozzle allows applicators to adjust their techniques for optimal results when treating wood-destroying pests and organisms.
