Compressibility

compressibility 2Compressibility, abbreviated as \(\beta \) (Greek symbol beta), also called coefficient of compressibility, a dimensionless number, measures the change in volume under external forces for any liquid.  Compressibility of a fluid increases with pressure and temperature and results in loss of volume output of pumps.  In control systems, compression of fluid provides a mass spring condition that limits system response.

\(\large{ \beta = \frac{1}{K}   }\) 
Symbol English Metric
\(\large{ \beta }\)  (Greek symbol beta) = compressibility \(\large{ dimensionless }\)
\(\large{  K }\) = bulk modulus \(\large{\frac{lbm}{in^2}}\)  \(\large{ Pa }\)
