Static Pressure Chart. Duct Design 2 — Available Static Pressure Energy Vanguard Pressure Drop is the available static pressure (ASP) allocated to the duct work Since the negative and positive signs identify the type of pressure measured, you can ignore them when adding the two values together

Sure, there are other ways of estimating or measuring airflow, but for commissioning a system in cooling, using static pressure and a blower chart is easy and accurate enough For properly designed systems with sufficient make-up air, the guidelines in the table below can be used for estimating static pressure.

Low Pressure Systems - where fan static pressures are less than 3 in WC (750 Pa) and duct velocities in general less than 1500 fpm (7.5 m/s) The amount of static pressure that the fan must overcome depends on the air velocity in the ductwork, the number of duct turns (and other resistive elements), and the duct length Use a duct calculator or the chart provided below to fig-ure the static pressure of 100 feet of a given diameter of duct at a given CFM
