Given information

Given values:

Water's bulk modulus,      
 
Water density,  

Table 9–1 in Chapter 9 contains the elastic and bulk moduli.

Table 10–1 in Chapter 10 contains the densities.

The speed of a longitudinal wave  in water can be obtained by using:
   
Here, is the bulk modulus of water and is its density. 
  
 

Step-by-step explanation

Step 1.

A longitudinal wave is one in which the medium's particles vibrate in the same direction as the wave's motion. The bulk modulus of a liquid, the Young's modulus of a solid, the pressure of a gas, and their density all affect the speed of a longitudinal wave.
