1. You are working as a flight-test engineer at the NASA Dryden Research Center. During the low-speed phase of the test program for the X-37, you know that the plane is flying at an altitude of 8 km. The pressure at station 1 is 1550 N/m2, gage; the pressure at station 2 is -3875 N/m2, gage. a) If station 1 is known to be at the stagnation point, what is the velocity of the airplane? b) What is the freestream dynamic pressure for this test condition? c) Assuming inviscid flow, what is the velocity of the air at the second station relative to the airplane? What is the Cp for this station? d) What is the Equivalent Airspeed (EAS)?

Abag of potato chips contains 2.00 l of air when it is sealed at sea level at a pressure of 1.00 atm and a temperature of 20.0 deg c. what will be the volume of the air in the bag if you take it with you, still sealed, to the mountains where the temperature is 7.00 deg c and atmospheric pressure is 70.0 kpa? assume that the bag behaves like a balloon and that the air in the bag is in thermal equilibrium with the outside air.
