If, in the system for Problem, the total drag on the object is measured to be 800 N/m of length normal to the direction of flow, and frictional forces at the walls are neglected, find the pressure difference between inlet and outlet sections.
Problem
A two-dimensional object is placed in a 4-ft-wide water tunnel as shown. The upstream velocity, v1, is uniform across the cross section. For the downstream velocity profile as shown, find the value of v2.
