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 of span. Calculate the circulation around the cylinder.
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 of span. Calculate the circulation around the cylinder.
Here V_{\infty} = 30\;m/s. Lift per unit span {L}’= 6\;N/m .We need to find the circulation \tau.{L}’=\rho _{\infty}V_{\infty}\tau
.
\tau=\frac{{L}’}{\rho_{\infty}V_{\infty}}=\frac{6}{1.23\times 30}=0.163\;m^{2}/s
