Homework Solution 4
1. Consider a thin airfoil with no camber but with a trailing-edge flap. The flap hinge is
located at x = x f , and the flap angle is f (positive flap angle is for downward
deflection).

1. An incompressible fluid flows steadily through a row of fixed airfoil-shaped surfaces
called a blade cascade. The surfaces are spaced h apart. The fluid velocity approaching
the cascade is V and makes an

Note to the Class:
As far as the second homework stands, I can concede the fact that I graded rather
harshly, but at the same time the work was no where near the quality of the last
homework. However, due to your drastic recent

1. A jet of water discharges vertically upward from a nozzle. The nozzle exit diameter is
2 cm, and the reservoir water level is 2 m above the nozzle exit. The jet supports a 500-g
plate, which is constrained by fricti
