Section $9\mathrm{.}1$ General External Flow Characteristics

$9\mathrm{.}1\mathrm{.}1$ WP Assume that water flowing past the equilateral triangular bar shown in Fig. P$9\mathrm{.}1\mathrm{.}1$ produces the pressure distributions indicated. Determine the lift and drag on the bar and the corresponding lift and drag coefficients $($based on frontal area$).$ Neglect shear forces.
