Quiz: 2.0 – Fundamentals of Misting

To what maximum operating pressure should you set the pump?

200 psi

Correct Incorrect Correct answer

250 psi

Correct Incorrect Correct answer

300 psi

Correct Incorrect Correct answer

As high as it will go

Correct Incorrect Correct answer

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

5 seconds

Correct Incorrect Correct answer

31 seconds

Correct Incorrect Correct answer

90 seconds

Correct Incorrect Correct answer

I didn’t know there was going to be test

Correct Incorrect Correct answer

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

300 psi and 60 milliliters per minute

Correct Incorrect Correct answer

200 psi and 40 milliliters per minute

Correct Incorrect Correct answer

250 psi and 50 milliliters per minute

Correct Incorrect Correct answer

I didn’t know there was going to be a test

Correct Incorrect Correct answer

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

Is imperative.

Correct Incorrect Correct answer

is not necessary if you have fewer than 35 nozzles on each run of 1/4" tubing.

Correct Incorrect Correct answer

is a good idea if the nozzle runs from the unit are very different in length and nozzle count.

Correct Incorrect Correct answer

can make it difficult to find a leak if the tubing is buried.

Correct Incorrect Correct answer

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

Auto Drain valve

Correct Incorrect Correct answer

Solenoid valve

Correct Incorrect Correct answer

Check valve

Correct Incorrect Correct answer

Bivalve

Correct Incorrect Correct answer

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

When you’ve got a tubing run of 10 feet with no nozzles

Correct Incorrect Correct answer

When you have to put more than 35 nozzles on a single run of 1/4" tubing

Correct Incorrect Correct answer

All the time

Correct Incorrect Correct answer

Never

Correct Incorrect Correct answer

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

Because you said so

Correct Incorrect Correct answer

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.

Correct Incorrect Correct answer

If you don’t, the whole thing could blow up.

Correct Incorrect Correct answer

I didn’t know there was going to be a test

Correct Incorrect Correct answer

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

Magic “flow increasing” beans

Correct Incorrect Correct answer

Teeing close to the unit and dividing the flow to reduce pressure drop

Correct Incorrect Correct answer

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?

Correct Incorrect Correct answer

Getting a bigger pump

Correct Incorrect Correct answer

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

Is caused by friction and increases as flow through the segment increases

Correct Incorrect Correct answer

Is greater than the drop in a 10 foot segment of 3/8” tubing with the same flow

Correct Incorrect Correct answer

Causes each nozzle along the circuit to have less flow than the one upstream of it

Correct Incorrect Correct answer

All of the above
