The 3 Basic Fan Laws - Eldridge

Sep 04, 2014 The speed ratio is 2. So the cube of that ratio becomes 8. So now you need to use a motor that will provide 80 HP which in this case is a 100 HP / 1800 RPM motor because there is no such thing as an 80 HP, 1800 RPM motor available. By the way, according to Fan Law 2, the Static Pressure (SP) increases as the square of the speed ratio.

The Difference Between An Axial And Radial Fan
