What are the usual air temperature and pressure settings used for testing the performance of a centrifugal fan?
In general, when a supplier performs a performance test on a centrifugal fan before engraving the nameplates, Normal Temperature and Pressure (NTP) is utilized as a standard condition. Because the density of air changes with altitude and temperature, the capacity, i.e., the mass flow rate of air (Kg/s) through the fan changes.
NTP: Temperature is 20°C
Pressure is 1atm (101.325 Kpa)
