Wind Tunnel Experiment Details
One inexpensive method to measure DP is to
create a Manometer.
Need total and static pressure ports. Partially fill a (Tygon) tube with water. Hook ends of tube to the two ports. As speed increases, the difference between water heights will
ncrease. (The total pressure will push
the water down.) Measure pressure
(inch H20) by measuring “h”.
Then: DP: 27.68 in H20 = 6895 N/m2 conversion factor
