What does MPS stand for?

What does MPS stand for?

• A. Meters per second
• B. Megnehelic gauge
• C. Mechanical draft speed
• D. Mass pressure scale

Answer: (A)

Understanding common unit abbreviations for velocity in ventilation is the key idea here. MPS stands for meters per second, a standard SI unit that describes how fast air moves through a dryer exhaust duct. This velocity measurement is what technicians use to assess airflow and draft in the venting system. The other terms aren’t correct interpretations of MPS: a magnihelic gauge is a device used to measure very low pressures, not a unit of speed; and the remaining options don’t correspond to a standard, widely used unit for airflow velocity. So the correct meaning is meters per second.
