The lift on a spinning circular cylinder in a freestream with a velocity of 30 m/s and at standard sea level conditions is 6 N/m
Evgesh-ka [11]

Answer:

The circulation around the cylinder is 0.163 \frac{m^{2} }{s}

Explanation:

Given :

Velocity of spinning cylinder v = 30 \frac{m}{s}

Sea level density \rho = 1.23 \frac{kg}{m^{3} }

Sea level span L = 6 \frac{N}{m}

Lift per unit circulation is given by,

  L = \rho v c

Where c = circulation around cylinder

   c = \frac{L}{\rho v}

   c = \frac{6}{1.23 \times 30}

   c = 0.163 \frac{m^{2} }{s}

Therefore, the circulation around the cylinder is 0.163 \frac{m^{2} }{s}
