Question
The Kutta condition states that bodies with sharp trailing edges will change this quantity to hold the stagnation point at the trailing edge. For 10 points each:
[10h] Name this quantity that is multiplied by fluid density and fluid velocity far upstream to give the lift per unit span according to the Kutta-Joukowski theorem.
ANSWER: circulation
[10m] The Kutta-Joukowski theorem applies when these entities are thin and have an infinite span. Wings are examples of these lift generating entities.
ANSWER: airfoils [or aerofoils]
[10e] Airfoils experience skin friction which contributes to a coefficient named for this force that opposes motion and counteracts thrust.
ANSWER: drag force [accept air resistance; accept fluid resistance; do NOT accept or prompt on “resistance” alone]
