What is VMD? - ANSWER-Volume Median Diameter
VMD tells you what? - ANSWER-The droplet diameter at which
half of the volume of the spray contains larger droplets and half
contains smaller droplets.
VMD is helpful for predicting what? - ANSWER-Nozzle tips
capacity to provide spray coverage.
VMD can also be used to describe in simpler terms? - ANSWER-
The "spread" of droplet sizes in a given droplet spectrum.

Settling velocity is what? - ANSWER-The rate at which a spray
droplet falls through the air toward the ground.
Another term for settling velocity is? - ANSWER-Fall Rate
Settling velocity is generally roughly proportional to what? -
ANSWER-The square of a droplets diameter.
The settling velocity of a 200 micron droplet is? - ANSWER-231
feet/minute
The settling velocity of a 20 micron droplet is - ANSWER-2.4
feet/minute
What can you adjust to alter spray droplet size? - ANSWER--
Nozzle type
-Orifice diameter
-Spray pattern angle
-Travel speed
, 4|Page
-Spray pressure
-Nozzle mounting angle
What are a few of the common nozzle types used in aerial
application? - ANSWER--Cone
-Fan
-Straight stream
-Rotary atomizers
Which spray pattern angle is less likely to create drift prone
droplets, 80 or 110 degree? - ANSWER-80 degree
Which spray pattern is less likely to produce drift prone droplets,
conical or fan? - ANSWER-Fan pattern
What influence does air shear have on spray droplets? -
ANSWER-Causes droplets to collide with each other an break up,
creating a greater number of drift prone droplets.
