How to calculate the power requirement of a centrifugal fan?
Once the static pressure, volume flow rate needed, and static efficiency of a selected fan are known, the power demand of a motor may be calculated using the following equation. Static Efficiency=(Static Pressure(Pa)×Volume Flow rate(m3/s))/(Brake Horse Power(W))

Before the invention of mechanical refrigeration (i.e., Vapour Compression Refrigeration Cycle VCRS) people from North American countries, Norway & Canada used to trade ice collected from icy freshwater lakes and ponds (called natural ice trade) to South American countries and the Southern US states during summer months. Ice was kept near the fan to cool the houses. The ice trucks supply the ice in terms of Tons and the truck visits once in every 24 Hrs.
The transition from horses to steam engines led to the birth of the horsepower unit similarly, the natural ice trade led to the birth of TR (Tons of Refrigeration).
