Duct System Design and Static Pressure

What is a key characteristic of a well-designed duct system?

• It should have high air speed.

• It should be silent and comfortable.

• It should have visible air flow.

• It should be noisy.

What is static pressure in a duct system?

• The pressure exerted by the system's fan.

• The noise level of the duct system.

• The speed of air through the duct.

• The temperature of the air in the duct.

How does increased static pressure affect air velocity in a duct?

• It decreases air velocity.

• It has no effect on air velocity.

• It makes air velocity unpredictable.

• It increases air velocity.

What is a common cause of hot or cold spots in a room?

• Low static pressure.

• Properly sized ducts.

• Improper duct design or sizing.

• Excessive air speed.

What should a properly designed duct system achieve in terms of room temperature?

• It should effectively heat and cool rooms in all seasons.

• It should maintain a constant temperature regardless of season.

• It should only heat rooms.

• It should only cool rooms.
