The circular-arc hydrofoil of problem (26) is placed at an angle of attack α= 0 degrees in a uniform water stream at 20o c. take u∞= 5 m/s and p∞= 120 kpa. determine:
(a) the lift coefficient, cl.
(b) the lift l per unit span length.
(c) the velocity magnitude and pressure at the points q1 and p1, where the hydrofoil intersects the y−axis. compare these values to u∞ and p∞.
