Question

An incompressible fluid flows past an impermeable flat plate with a uniform inlet profile (U₀ ) and a cubic polynomial exit profile:

where  

Compute the volumetric flow rate (Q=? cm³/s) across the top surface of the control volume.

Consider the width of the solid plate (into paper) to be b=10 cm.

U₀= 15 cm/s

Air at 20°C and 1 atm flows in a 25-cm-diameter duct at V₁=20 m/s. The exit is choked by a 90° cone.
