$7\mathrm{.}9\mathrm{.}9$WP A $\frac{1}{10}-$scale model of an airplane is tested in a wind tunnel at $70F$ and $14\mathrm{.}40$ psia. The model test results are:

$\backslash$table$[[$Velocity $($mph$),0,50,100,150,200],[$Drag $($lb$),0,5,21,46,85]]$

Find the corresponding airplane velocities and drags if only fluid compressibility is important and the airplane is flying in the U$.$S$.$ Standard Atmosphere at $30,000$ ft$.$ Assume that the air is an ideal gas.
