mE 2 #1, An airplanc is flying at an altitude of 12000 m. Determine the gage pressure at the stagnation point on the nose of the plane if the speed of the plane is 200 km/h. What would be the gage pressure at a point on the surface of plane where the relative wind speed is 250 kr/h? Solve ; At an aé¢ituale of L20bO™N , p = Fam = 19.4 KPs, ; fi = 63/2 fag im .
