Abstract

A fan efficiency monitoring system and method utilizes the measured temperature and pressure differential a fan to calculate and display fan efficiency relative to the temperature differential in an isentropic process at the same inlet temperature and pressure differential. The computed fan efficiency is displayed proximal the fan or at a remote operator's station.
