Dynamic pressure is the kinetic energy of a flowing fluid - liquid or gas - per unit volume - and can be expressed as. p d = 1/2 ρ v 2 (1) where . p d = dynamic pressure (N/m 2 (Pa), lb f /ft 2 (psf)) ρ = density of fluid (kg/m 3, slugs /ft 3) v = velocity (m/s, ft/s) Dynamic Pressure Calculator - SI Units
The chart below can be used to estimate friction loss in air ducts. The default values are for air flow 400 cfm (680 m 3 /h) , duct size 8 in (200 mm) and friction loss 0.28 inH2O/100ft (2.3 Pa/m) .

Units of pressure. As stated earlier, the SI unit for pressure is the pascal (Pa), where \[1\; Pa = 1\; N/m^{2} \ldotp\] In addition to the pascal, many other units for pressure are in common use (Table \(\PageIndex{1}\)). In meteorology, atmospheric pressure is often described in the unit of millibars (mb), where
Purpose and Learning Objectives. The purpose of this presentation is to provide industry professionals with an overview of the basic concepts and relationships between airflow and pressure, and how these concepts are affected by various outside factors in regard to fans.
