Pitot tube - measure airflow speed



Example uses: Find areas of separated and attached flow, measure thickness of boundary layers, assess airflow direction for setting wing angles

Equipment: model aircraft pitot tube, sensitive Magnehelic gauge

Complexity: easy to do and interpretation of results straightforward

Comment: allows assessment of attached / separated flow on undertray out of sight of wool tufts

Cost: $10 (pitot) + $50 (gauge)

(I must credit F1 aerodynamicist Willem Toet for bringing these pitot tubes to my attention. He mentioned them to me when describing some low cost data logging equipment being used in student-based racing cars. I didn't go for the data logging equipment, but loved the pitot tubes!)
