The incorrect equation for the normal shock equation is_______(a) ρ1u

1.	The incorrect equation for the normal shock equation is_______(a) ρ1u1=ρ2u2(b) p1+ρ1u\(_1^2\)=p2+ρ2u\(_2^2\)(c) h1+\(\frac {u_1^2}{2}\)=h2+\(\frac {u_2^2}{2}\)(d) ∇.v=0The question was posed to me in an international level competition.My query is from The Basic Normal Shock Equations topic in portion Normal Shock Waves of Aerodynamics
Answer» CORRECT CHOICE is (d) ∇.v=0 Explanation: The normal shock WAVE analysis has the basic EQUATIONS which are the continuity equation ρ1u1=ρ2u2, momentum equation p1+ρ1u\(_1^2\)=p2+ρ2u\(_2^2\) and the energy equation h1+\(\frac {u_1^2}{2}\)=h2+\(\frac {u_2^2}{2}\). The equation ∇.v=0 is the incompressible flow equation for a steady flow. The normal shock wave is a compressible flow.
