&gt;Drag on a body in a fluid is:<br/>
&gt;<br/>
&gt;D = Cd*pi*r^2*rho*Vo^2<br/>
&gt;<br/>
&gt;Cd = coefficient of drag of the swallow<br/>
&gt;pi = 3.1415...<br/>
&gt;r = radius of bird cross-section (approximating as a circle)<br/>
&gt;rho = viscosity of air<br/>
&gt;Vo = velocity<br/>
&gt;<br/>
&gt;For steady state flight, D (drag) = T (thrust), so:<br/>
&gt;<br/>
&gt;Vo = sqrt(T/Cd*pi*r^2*rho)<br/>
