FSA Calculator


Here is a simple Excel spreadsheet that calculates FSA of a ducted fan. I see people ask how to calculate FSA a lot. This spreadsheet will give you 100% FSA down to 70% FSA in 5% increments. Only input the diameters of the fan shroud and the fan hub (green cells). The fan hub diameter should be the largest diameter of the hub as some fans have a pointed tip.

I have updated this spreadsheet. It now also calculates exhaust diameter at different percentages of FSA from 100% down to 70% in 5% steps. This is done for both a single exhaust outlet and a bifurcated (two outlets from one fan) exhaust.

Somehow I deleted this spreadsheet a while back. Sorry about that.
