1.	In terms of compressibility, the density change when pressure of the fluid increases is ______(a) Density increases(b) Density decreases(c) Density is constant(d) Insufficient dataThe question was asked in a job interview.This interesting question is from Definition of Compressibility topic in chapter Compressible Flow – Preliminary Aspects of Aerodynamics
Answer» Correct answer is (a) Density increases For explanation: The formula for compressibility when expressed in terms of density GIVES a DIRECT RELATION between pressure change and density change. i.e. dρ = ρ τ DP. HENCE, when the pressure increases density of the fluid increases.
