Variable 28 – Calculation of modulus of elasticity of medium

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

Depending density

Density at 20°C and 5bar:

Modulus of elasticity:
