The shock waves on a vehicle in supersonic flight cause a component ofdrag called supersonic wave drag Dw. Define the wave-drag coefficient asCD,w = Dw/q∞S, where S is a suitable reference area for the body. Insupersonic flight, the flow is governed in part by its thermodynamicproperties, given by the specific heats at constant pressure cp and atconstant volume cv. Define the ratio cp/cv ≡ γ . Using Buckingham’spi theorem, show that CD,w = f (M∞, γ ). Neglect the influence of friction.

Question
The shock waves on a vehicle in supersonic flight cause a component of
drag called supersonic wave drag Dw. Define the wave-drag coefficient as
CD,w = Dw/q∞S, where S is a suitable reference area for the body. In
supersonic flight, the flow is governed in part by its thermodynamic
properties, given by the specific heats at constant pressure cp and at
constant volume cv. Define the ratio cp/cv ≡ γ . Using Buckingham’s
pi theorem, show that CD,w = f (M∞, γ ). Neglect the influence of friction.
