Converting Velocity Pressure into Cubic Feet per Minute (CFM)

Almost every building in the United States has a HVAC (Heating, ventilation, and air conditioning) system that relies on balancing Velocity Pressure calculated CFM to properly control atmosphere building. This is ensured tested by Field Engineers whose job it maintain efficiency proper output of these systems. These systems are used improve indoor quality, moisture condensation, contaminants while satisfying comfort needs occupants. Just with any mechanical system, function efficiently multiple formulas derived from calculus physics. Every equipped meet certain threshold movement, measured Cubic Feet per Minute (CFM), creates stable comfortable testing Pressure. base reading takes understand adjust movement within guarantee overall best quality an environment. Once measurement Pressure, inches water column (in-WC) using tool called Flow Hood or Straight Pitot Tube, taken then you can start calculate flow readings test if fan producing correct amount was built produce support. done series algebraic equations area velocity into consideration. When solving formulas, be determined its fans ideal airflow accurately precise environment for
