Consider a wing mounted in the test-section of a subsonic wind tunnel. The velocity of the airflow is 160 ft/s, and the velocity at a point on the wing is 314 ft/s. If the test-section air temperature is 510°R and the flow velocity is increased to 426 ft/s, what is the pressure coefficient at the same point? (Round the final answer to three decimal places.)

The airfoil data in Appendix D were obtained in the NACA two-dimensional Low Turbulence Pressure Tunnel...
The airfoil data in Appendix D were obtained in the NACA two-dimensional Low Turbulence Pressure Tunnel at the NACA Langley Memorial Laboratory. This facility went into operation in Spring 1941. The tunnel was especially designed for airfoil testing, with a test section 3 ft wide and 7.5 ft high. The wing models spanned the entire test section of width 3 ft, sso that the flow over the model was essentially two-dimensional. The chord length of the models was 2 ft....

A finite wing with an area of 2.0 ft2, an aspect ratio of 7.0 and a span efficiency factor of 0.96 is mounted in a wind tunnel where the test section flow velocity is 110 ft/s at standard sea-level conditions. When the wing is pitched to a = -20, no lift is measured. When the wing is pitched to a = 10.00, a lift of 20 lbs is measured. Determine the lift curve slope for the airfoil (i.e., the infinite...

A wing-body model is tested in a wind tunnel with a flow of 100 m/s at standard sea-level conditions. The wing area is 1.5 m2 and the mean aerodynamic chord length is 0.45 m. Measurements of lift force, L, and moment about the center of gravity, M CG are made using the wind tunnel force balance. B1(a) When the lift is zero, the moment about the center of gravity is measured to be, MCG = −12.4 Nm . At another...

Consider the flow of oil at 10?C in a 40-cm diameter pipeline at an average velocity of 0.5 m/s. A 1500-m long section of the pipeline passes through icy waters of a lake at 0?C. Disregarding the thermal resistance of the pipe material, determine (a) the temperature of the oil when the pipe leaves the lake (b) the rate of heat transfer from the oil and (c) the pressure losses in the pipe. Assume the flow is hydro-dynamically fully developed.

PART A) Consider a sea lion swimming horizontally in 20C sea water. It is neutrally buoyant. Its mass is 200kg, body surface area 2.1 m2, and drag coefficient Co= 0.0038. After accelerating from rest for a while (about half minute or so), the animal reaches a state of terminal velocity Uterm of 1.1 m/.s. Calculate the drag and the thrust forces at that moment. PART B) The sea lion studied in the previous question is now vertically diving. It is...
