Answer 1

Answer:

$\sf\fbox{\underline\red{Answer:-}}$

♤Feet per minute (FPM)♤

Air velocity (distance traveled per unit of time) is most often expressed in feet per minute (FPM). Multiplying air velocity by the area of a duct allows you to determine the air volume flowing past a point in the duct per unit of time. Volume flow is generally measured in cubic feet per minute (CFM).
