Question:

Performance characteristics of a Howden Buffalo axial flow fan are presented below. The fan is used to power a wind tunnel with \(1-\mathrm{ft}\)-square test section. The tunnel consists of a smooth inlet contraction, two screens each with loss coefficient \(K=0.12\), the test section, and a diffuser where the cross section is expanded to 24-in.-diameter at the fan inlet. Flow from the fan is discharged back to the room.


Calculate and plot the system characteristic curve of pressure loss versus volume flow rate. Estimate the maximum air flow speed available in this wind tunnel test section.
