1.28. The performance curve for the fan of Problem 1.27 can be approx- imated by a straight line through its BEP (using techniques devel- oped in Chapter 7). The curve is Aps = 4488 – 166Q, with ApT in Pa and Q in m³/s. If this fan is connected to a 1-m dia- meter duct (f = 0.045) whose length is 66 m, what flow rate will result? %3D
