Cauchy Number
Cauchy number, abbreviated as Ca, a dimensionless number, is the ratio of inertial force to compressibility force in a flow. When the compressibility is important the elastic forces must be considered along with inertial forces.

\(\large{ Ca }\) = Cauchy number | \(\large{dimensionless}\) | |
\(\large{ B }\) = bulk modulus elasticity | \(\large{\frac{lbm}{in^2}}\) | \(\large{Pa}\) |
\(\large{ \rho }\) (Greek symbol rho) = density | \(\large{\frac{lbm}{ft^3}}\) | \(\large{\frac{kg}{m^3}}\) |
\(\large{ v }\) = velocity of flow | \(\large{\frac{ft}{sec}}\) | \(\large{\frac{m}{s}}\) |
