Based on the defi nition in Problem 5.55, use the thermodynamic web to come up with an expression and a value for [Vsound] in water at 20°C. Use the steam tables for thermodynamic property data of liquid water.

Problem 5.55

The speed of sound, Vsound [m/s], is formally equal to the partial derivative of pressure with respect to density at constant entropy:

Show that,

where MW is the molecular weight.
