WebTo calculate the air change in a room, the airflow is measured (CFM) and multiplied by 60 minutes per hour. It is then divided by the volume of the room you wish to measure (in cubic feet): Air Changes / hr = (CFM x 60 minutes) / Volume of the room (cubic feet) In simpler words, we change the CFM or Cubic Feet per Minute into CFH or Cubic Feet ... WebWind speed is measured with an anemometer. Most anemometers have four horizontal shafts arranged like the spokes of a wheel. The end of each shaft is cup-shaped. The wind pushes the concave side of the cup more than the convex side, so the anemometer spins in the wind. The faster the anemometer is spinning, the stronger the wind.
