Question
Please solve question below according to the graph
elevation 6 ft above the lake? Air is drawn into a small open-circuit wing tunnel as shown in Fig. Atmospheric pressure is 98,7 kPa (abs) and the temperature is 27 degree C. If viscous effects are negligible, determine the pressure at the stagnation point on the nose of the airplane. Also determine the manometer reading, h, for the manometer attached to the static pressure tap within the test section of the wind tunnel if the air velocity within the test section is 50 m/s.Explanation / Answer
additonal pessure at test section = .5* rho * v^2
=.5*1.225*50^2=1531.25Pa
change in coulmn hieght = additional pressure /( rho *g)
= 1531.25/(1000*10)
=.15m
= 15 cm
