Poorly thought out, not useful – Greenheck Toolbox Review

Fan law function has few real world uses, especially if used in the field. One must know brake horsepower to run the calc. Who has that information in hand if one does not have submittal or fan curve in front if them? This functions is not applicable for typical VAV systems with a duct static pressure control set point. Without this, erroneous fan power, as well as fan rpm, will result. The ductulator needs a major overhaul. Good thing it is free...that is what it is worth.
