Transcribed Image Text:
Consider a source with a strength of A = 16 m²/s, placed in a free stream velocity of
16 m/s, pressure of 92 kPa, and density of 1.05 kg/m³, above a flat plate. The source is
located at y = 0.5 m. To model the effect of the plate, we can place a second source
of equal strength at y = -0.5 m, which results in a horizontal streamline between the two
sources. A section of the streamline can be used to model the flat plate which has a
length of 0.8 m placed in the flow at y=0 and centered between the two sources. If the
pressure on the bottom of the flat plate is 92 kPa and the pressure on the top of the flat
plate is a function of the velocity distribution, compute the coefficient of lift per unit span
for the flat plate. (Answer to 2 decimal places.)
