Calculation of the modulus of elasticity of liquids
From the relation of the speed of sound in liquids, it follows:
![]()
E= Modulus of elasticity of liquid
and thus for E
![]()
dr/dp = Change of density in cours of pressure = Compressibility of liquid
Example for water at 20°C and 5bar
Replacing the differentials by differences
