WebJul 24, 2013 · Fan laws are a set of equations applied to geometrically identical fans for scaling and performance calculations. Published fan laws apply to applications where a fan’s air flow rate and pressure are independent of the Reynolds number. Web1. Read the New York Blower Fan Laws Document. Pay special attention to the Pressure and Velocity, and the Fan Curve and System Curve sections. Review the sketch provided and then download the sketch. Look at the graph axis (Static pressure is vertical [Y]and cubic feet per minute is horizontal [X]). Read and learn the scale used for each axis. 2.
Web(The fan performance chart shows performance curves for a series of fan speeds.) At fan speed N1, the fan will operate along the N1 performance curve as shown in Figure 5.7. The fan's actual operating point on this curve will depend on the system resistance; fan’s operating point at “A” is flow (Q1) against pressure (P1). Figure 5.7 ...
