WebA typical grille with about 16 inches by 25 inches size has a free area of around 80%. So, if we recalculate the grille area based on 80% free area, the result is as follow: Grille Area (sq.in) = Airflow (cfm) ÷ Face Velocity (fpm) ÷ Grille Free Area (%) x 144 Grille Area (sq.in) = 1050 ÷ 500 ÷ 0.8 x 144 Grille Area (sq.in) = 378 sq.in WebApr 12, 2024 · Calculating CFM will require a calculator unless you are lucky enough to be a math genius Here was the response. “Based on physical gas law, common sense decreased volume results in increased pressure (and also temperature). P = pressure V = volume K = constant So: P = K* (1/V) 90psi = K* (1/5 cubic feet) Solving for K, we get a value of K = 450
