Air Flow Dos and Don’ts: Air Flow Made Simple!

2. True or False: If a PSC (Permanent Split Capacitor) motor is up against more static pressure than it can handle, the amperage draw will go up.

3. Which term refers to "straight air" that has had the chance to stabilize after leaving the blower?

4. About how many inches of water column ("wc) are equal to 1 PSI?

5. When measuring static pressure with a straight tube (instead of a specialized tip), at what angle should the tube be pointed into the airflow?

6. True or False: A "pitot tube" and a "static pressure tip" are NOT the same tool and should not be used interchangeably.

7. To achieve big results with flex duct, what is Joey's recommendation for sizing when converting from rigid duct?

8. For a PSC motor, what is the recommended starting static pressure to allow room for future dirt buildup?

9. True or False: To improve the efficiency of a duct elbow, it is more important to curve or miter the inside turn than the outside turn.

10. To ensure "straight air" for an accurate static pressure reading, how many feet of uninterrupted duct should ideally exist after the blower before making a turn?
