Unformatted text preview: Find the stream function corresponding to the above potential ii. Plot the streamlines, including the streamline passing through the stagnation point. 6) An airplane flies at sea level. The pitot tube reads a pressure of 1.03 atm. What is the air speed of the plane? 7) A circular cross section tube with radius 1cm has a narrow section with minimum radius 0.5cm. The pressure difference between a point upstream from the narrows and the throat is 450 Pa. The fluid is air. What is the volume flow rate in the tube in liters/min? 8) A blowdown wind tunnel test section has an air speed of 150mph and a pressure of 1 atm. It is fed by a large pressurized tank. What does the pressure in the tank need to be?...
