    • The author looking up nozzle rates during a spring calibration. The operator was running at 190 psi, but the catalogue only listed 180 psi and 200 psi. When span is only 20 psi, it’s fairly safe to approximate the output. When the table only lists in 50 psi increments, it is more difficult to determine the rate without testing the output. This issue usually occurs at pressures above 200 psi, and that’s very high for most horticultural operations. Consider using a lower operating pressure, if possible. How to use Airblast Nozzle Tables

  • Thermal Turbulence allows particle-laden warm air to rise and clean cool air to fall. This disperses air-borne particles like pollution or pesticide.
  • The Earth’s Atmosphere. The illustration of the Earth is to scale, but the landscape is not. Our focus in on the Surface Boundary Layer.
  • Inversions occur to some extent every day. It’s the intense and prolonged inversions we want to be especially aware of. On this hypothetical 24 hour clock, we see the inversion fades in the morning and grows in intensity through the evening. Do you spray in the morning or at night? Be mindful or pollinating insects, but when there’s a strong inversion, consider night/morning spraying over evening/night.
  • If you see fog, dew or frost, you’re already in an inversion. The air has become cold enough to condense or even freeze water.
  • Thermal Turbulence is suppressed during a Temperature Inversion. Particle-laden cool air at the surface cannot rise, and warm, clean air cannot fall. No dispersion occurs, and the concentrated, particle-laden air tends to move downhill or laterally with light winds.
  • A hot-air balloon is a metaphor for convection cells that create thermal turbulence.
