| HPnew = HPoriginal x (Speed New/Speed Original)3
Example: Original HP = 7.5 Original Blower Speed 900 RPM New Blower Speed 750 RPM |
 |
Determine new HP
HPnew = 7.5 x (750/900)3 or 7.5 x (750/900) x (750/900) x (750/900) = 7.5 x .83 x .83 x .83 = 7.5 x .57 = 4.3 HP Note: Driving Energy Requirement (Watts) go up and down at approximately the same rate as HP. |
