Question

Air is drawn into the smaill open-circuit wing tunnel as shown. Atmospheric pressure is 98.7 kPa (abs) and the temperature is 27degrees C. Vicous effects are negligible. h=.146 m. Determine the pressure at the stagnation point on the nose of the plane.

Air is drawn into the smaill open-circuit wing tunnel as shown. Atmospheric pressure is 98.7 kPa (abs) and the temperature is 27degrees C. Vicous effects are negligible. h=.146 m. Determine the pressure at the stagnation point on the nose of the plane.

Explanation / Answer

pressure(stagnation)=P(atmosphere)-1000*9.81*0.146=98.7*10^3-(1000*9.81*0.146)

=9.72 kPa
