The ratio of Inertia force to elastic force is called as ________(a) R

1.	The ratio of Inertia force to elastic force is called as ________(a) Reynold’s number(b) Froude number(c) Weber number(d) Mach numberThe question was posed to me during a job interview.I would like to ask this question from Doublet Flow topic in portion Inviscid & Incompressible Flow of Aerodynamics
Answer» CORRECT option is (d) Mach number Easy explanation: The inertial force is given by-ρL^2V2^2 and the ELASTIC force is given by- KXA. Therefore, the mach number is given by- ρ* L^2* V^2/KXA which GIVES, V^2/(K/ρ).
