WebFeb 1, 2010 · Building differential static pressure commonly is measured with a sensor with two ports: a high-pressure port and a low-pressure port. Tubing extends from both ports. Commonly, low-port tubing is extended to the outside of a building, while high-port tubing is extended to an interior space. WebOct 29, 2013 · Ps = Static pressure, in. wg Pt = Total pressure, in. wg BHP = Fan power input, hp. Fan static and total efficiency (Figure 1) can be plotted along with the fan pressure curves. The peak total efficiency occurs at the top of the “bell” shaped efficiency curve. This peak total efficiency is used to determine the FEG value.

Webpressure, and input power as measured per AMCA Standard 210. It does not take into effect the efficiency of the drive (belt drive) or the motor. Fan efficiency is defined as the air power divided by the fan input power. Both Static and Total Efficiency can be calculated from fan performance data as follows: Where: CFM 3= Fan flow rate, ft /min WebGreenheck Product Application Guide 2 ¨ Fan Application No. FA/115-02 pressure across both fans will be the sum of the individual total pressure of each fan. Total pressures are used instead of static pressure because the fans can actually be different sizes and a change in fan or connecting duct areas has an influence upon static pressure values.
