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 \(\tau\).\[{L}’=\rho _{\infty}V_{\infty}\tau\].
\[\tau=\frac{{L}’}{\rho_{\infty}V_{\infty}}=\frac{6}{1.23\times 30}=0.163\;m^{2}/s\]
