Answer Key : (D) -

(D) $\operatorname{NACA} 2512$



Next Question :

For a laminar incompressible flow past a flat plate at zero angle of attack, the variation of skin friction drag coefficient $\left(\mathrm{C}_{\mathrm{f}}\right)$ with Reynolds number based on the chord length $\left(\mathrm{Re}_{\mathrm{c}}\right)$ can be expressed as
(A) $C_{f} \propto \sqrt{\operatorname{Re}_{c}}$
(B) $\mathrm{C}_{\mathrm{f}} \propto \mathrm{Re}_{\mathrm{c}}$
(C) $\mathrm{C}_{\mathrm{f}} \propto 1 / \sqrt{\mathrm{Re}_{\mathrm{c}}}$
(D) $C_{f} \propto 1 / \operatorname{Re}_{c}$
