Question
Assume an inviscid, incompressible flow. Also, standard sea level density and pressure are 1.23 kg/m3 (0.002377 slug/ft3) and 1.01 × 105 N/m2(2116 lb/ft2), respectively.
Consider the flow field over a circular cylinder mounted perpendicular to
the flow in the test section of a low-speed subsonic wind tunnel. At
standard sea level conditions, if the flow velocity at some region of the
flow field exceeds about 250 mi/h, compressibility begins to have an effect
in that region. Calculate the velocity of the flow in the test section of the
wind tunnel above which compressibility effects begin to become important, i.e., above which we cannot accurately assume totally
incompressible flow over the cylinder for the wind tunnel tests.
