An airfoil is being tested in a low-speed subsonic wind tunnel. The velocity of the flow in the test section is 76 ft/s, and the conditions are standard sea level. If the pressure at a point on the airfoil is 2,114 lb/ft2, what is the value of the pressure coefficient? (2 decimals) Use P=2116.8 psf and ρ=0.002377 slug/ft3 for SSLC pressure and density. Round off answer to the nearest hundredths, if the answer is negative include the negative sign.

Question

An airfoil is being tested in a low-speed subsonic wind tunnel. The velocity of the flow in the test section is 76 ft/s, and the conditions are standard sea level. If the pressure at a point on the airfoil is 2,114 lb/ft², what is the value of the pressure coefficient? (2 decimals) Use P=2116.8 psf and ρ=0.002377 slug/ft³ for SSLC pressure and density. Round off answer to the nearest hundredths, if the answer is negative include the negative sign.
