Fan Laws and System Curves
This is an information sheet presented in a newsletter format by the New York Blower Company.
The purpose of this Engineering Letter is to explain the basis and application of the rules used to predict fan performance in a given system. With a basic understanding of these rules, the performance of a fan can be quickly calculated for various conditions.
Whilst it is in imperial, I think it is well written and easily explains the basic principles of fan laws and curves.
