Quiz: 2.0 - Fundamentals of Misting

To what maximum operating pressure should you set the pump?

If there is no wind, about how long does it take MistAway’s 40 micron droplet to fall 5 feet?

What are the minimum pressure and flow rate targets for each nozzle on the circuit?

Choose all that apply. “Looping” the nozzle circuit …

A. Is imperative.
B. is not necessary if you have fewer than 35 nozzles on each run of 1/4" tubing.
C. is a good idea if the nozzle runs from the unit are very different in length and nozzle count.
D. can make it difficult to find a leak if the tubing is buried.

What type of valve does MistAway use to agitate the reservoir contents, hold fluid in the lines when the pump is shut off, and stop a siphon

When should you use 3/8″ tubing to boost the pressure in the nozzle circuit?

Why should you limit the number of nozzles on a single run of ¼” tubing to a maximum of 35?

Because you said so
If you install more than 35 nozzles, the resulting pressure drop will reduce the flow of most of the nozzles on the run to less than the Target Misting Zone minimum of 40 ml/min and the system won’t put out as much mist as it should.
If you don’t, the whole thing could blow up.
I didn’t know there was going to be a test

What is the best way to increase the flow out of the nozzle circuit?

Magic "flow increasing" beans
Teeing close to the unit and dividing the flow to reduce pressure drop
Closing the pump bypass as far as it will go and increasing the pressure at the pump. I mean really cranking it up. Who cares what the pressure is?
Getting a bigger pump

The pressure drop in a 10 foot segment of ¼” tubing …

Is caused by friction and increases as flow through the segment increases
Is greater than the drop in a 10 foot segment of 3/8 tubing with the same flow
Causes each nozzle along the circuit to have less flow than the one upstream of it
All of the above
