Given a two-dimensional blunt wedge immersed in a water stream, velocity profiles are measured both at the upstream and downstream Sections 1 and 2 using a streamline- bounded control volume (i.e., one that forms a streamtube). Determine (a) the vertical dimension of the upstream station, h; and (b) the total drag coefficient, which is dominated by the form drag, if the vertical dimension at the downstream station is 8-0.32, and the unit depth (in the z-direction) is W. Hints: The CV shown is only for half of the domain; the wedge is not a slender body; and the lincar velocity distribution at Section 2 in the upper half of the domain may be approximated by: u(x)=(1+24).
