The continuity equation for a compressible fluid is:(A → area), (V → velocity), (ρ → density)

A. \({A_1}{V_1} = {A_2}{V_2}\)
B. \(ρ_1 A_1 V_1=ρ_2 A_2 V_2\)
C. \(\frac{{{A_1}{V_1}}}{{{\rho _1}}} = \frac{{{A_2}{V_2}}}{{{\rho _2}}}\)
D. \(\frac{{{\rho _1}{A_1}}}{{{V_1}}} = \frac{{{\rho _2}{A_2}}}{{{V_2}}}\)
Answer» C. \(\frac{{{A_1}{V_1}}}{{{\rho _1}}} = \frac{{{A_2}{V_2}}}{{{\rho _2}}}\)
