Power Required (P_r)

Power Required << refers to the amount of power necessary to Lift (L) the aircraft given a set Weight (W) and Drag Polar produced by the aircraft; often has a lesser velocity than ^f7f63b general equation ;; $P_r=TV=DV$

Minimum Power Required equation ;; $\frac{4C_{d0}W}{\sqrt{\frac{3C_{d0}}{k}}}\times \sqrt{\frac{2W}{\rho s{C}_l}}$ relations ;; $2C_{d0}=C_{di}$ , $C_l=\sqrt{\frac{3C_{d0}}{k}}$

$V$ @ $P_a$ = $\frac{P_a}{\frac{W}{\frac{\sqrt{\frac{3C_{d0}}{k}}}{4C_{d0}}}}$
