Question

Find the change in volume which 1 m of water will undergo when takes
surface, to the bottom of sea 1 km deep. Given the elasticity of water is 20,000 atmosphere.
1-013 * 10% Nm
Solution. Here, V=1 m?:p=hpg=10° 10' 9-8 = 9.8 x 106 Nm?​

Answer 1

Answer:

Explanation:

Volume   V=1 m  

3

 

Bulk modulus   B=20000 N/m  

2

 

Excess pressure at 1 km depth,     ΔP=ρgh=1000×10×1000=10  

7

 N/m  

2

 

Using    B=  

ΔV

−VΔP

​

 

Or     20000=  

ΔV

−1×10

​

 

ΔV=−2×10
