$1\mathrm{.}9$ Consider two different flows over geometrically similar airfoil shapes, one airfoil being twice the size of the other. The flow over the smaller airfoil has freestream properties given by $T_{}=200K,{}_{}=1\mathrm{.}23k\frac{g}{m^3},$ and $V_{}=100\frac{m}{s}.$ The flow over the larger airfoil is described by $T_{}=800K,{}_{}=1\mathrm{.}739k\frac{g}{m^3},$ and $V_{}=200\frac{m}{s}.$ Assume that both $$ and a are proportional to $T^{\frac{1}{2}}.$ Are the two flows dynamically similar?
