Question 1:
In a wind tunnel test of flow over a wing section, air enters the test section at a speed of 54 m s1 and a pressure of 942 kPa.
Assuming Bernoulli's principle applies to the flow, what is the pressure at the stagnation point on the wing surface if the air
density is 1.16 kg m 3? The answer should have units of kPa.
