Ideal Fluid Flow

What is Magnus effect? A cylinder with $300 \text{ mm}$ diameter with a circulation $\Gamma$ is placed in free stream with uniform velocity of $5 \text{ m/s}$. Calculate the value of $\Gamma$ when both the stagnation points coincide on the body. Also calculate the lift acting on the cylinder. Take $\rho_{air} = 1.2 \text{ kg/m}^3$.

A Rankine oval of $2 \text{ m}$ long and $1 \text{ m}$ high is immersed in a stream of $10 \text{ m/s}$, as in Fig. 6(b). Determine the velocity at point A and the location of point B where a particle approaching the stagnation point achieves its maximum deceleration.
