The flat plate of Problem 9.18 is turned so that the 3-ft

side is parallel to the flow (the width becomes 10 ft). Should we

expect that the drag increases or decreases? Why? The trailing

edge boundary-layer thickness is now δ 5 0.6 in. Assume again

that the velocity profile is linear and that the flow is twodimensional (flow conditions are independent of z). Repeat

the analysis of Problem 9.18.
