Loren Cook Fan Law Calculator

The Fan Law Calculator is a convenient tool for mechanical engineers, test and balance contractors, and field tradesmen. Input the four existing field conditions (cfm, rpm, static pressure and horsepower) and one value of a new desired performance condition. The Fan Law Calculator then performs the calculations for the new conditions. Users are advised to verify maximum rpm limits of a product before increasing speeds.

Great app, works fantastic. Saves on time like you wouldn't believe once you know how SP works.

Awesome app!!!!!! Can you please update this app so that the new static pressure is displayed in thousandths instead of hundredths. I like to split hairs while at work plus it looks better on our documents. It would be greatly appreciated

Easy to use, and after the update, no more force closes. Thanks! (This is on an HTC Droid Incredible version 1.2)

GREAT Tool to use figuring the effects of changing motor speed on a fan. Easy way to figure new horsepower requirements when looking for a higher or lower air flow.

After entering cfm, it fc when entering sp starting with a period.

Limited use, just use the fan curve.
