About this app

Greenheck Fan Law Calculator gives you the capability to quickly determine new flow rates when performance changes need to be done to an existing unit. Simply input the existing specifications for rpm, cfm, static pressure, and horse power. Next input the desired performance (cfm or rpm) and the remaining values will automatically calculate using standard fan laws.

Ratings and reviews

I use this app as reference for work as HVAC designer, and I liked. But now I try to install in my new Razr phone it say it's not compatible and not able to install. :(

It's great I love it ❤❤❤❤❤❤❤❤

Screens do not render correctly on Moto Droid4. Seems like it could be valuable tool, but it is nearly impossible to use on my device because there are multiple layers of text that run over each other, and entry fields overlap.
