Tunnel Pedo-Tube Anemometer Testing
Prep:
Ambient Temp: 71.6 °F
Presure: 985.6 mb (absolute)
Offset: 0.027 mb
Tests:
All Three Fans Starting Flow: 16.50 - 16.60 m/s
First Run (16.20 m/s):
Edge: Δp = 0.7
1': Δp = 1.1
2': Δp = 1.1
3': Δp = 0.8
4': Δp = 0.8
5': Δp = 0.8
Second Run (16.30 -16.40 m/s)
Edge: Δp = 1.17
1': Δp = 1.16
2': Δp = 1.05
3': Δp = 0.97
4': Δp = 0.66
Very turbulent flow. 1 fan on: 6.66 m/s.
Measuring wind speed across fan opening, higher wind speeds recorded at edges compared to middle.
Max (Edges): 20.70 m/s
Min (Middle): 15.85 m/s
