Tr = 0.5SV^2(Cdo+((4W^2)/(AR*e*pi*V^4*p^2)))*p
Please help me isolate V in this Thrust required equation
Your equation is essentially of this form:
$\displaystyle T_r = Av^2 + \frac B {v^2}$
Where $\displaystyle A$ and $\displaystyle B$ are constants. You can rearrange to put it into this form:
$\displaystyle Av^4 -T_r v^2+B = 0$
Now solve for v^2 using the quadratic equation.
