Question

determinemine the bulk modulus of elascity of a liquid if the pressure of the liquid is decreased
from 7oN/cm^2 to 130 N/cm^2. The volume of a
liquid decreases by 0.15 percent​

Answer 1

Explanation:

Given Determine the bulk modulus of elasticity of a liquid if the pressure of the liquid is decreased from 70 N/cm^2 to 130 N/cm^2. The volume of a liquid decreases by 0.15 percent

• Given Initial pressure = 70 N / cm^2
•           Final pressure = 130 N/cm^2
• Increase in pressure = dp = 130 – 70 = 60
• So decrease in volume = 0.15%
•        So – dv / v = 0.15 / 100
• Now the bulk modulus of elasticity of liquid K = dp / - dv / v
•                            Or K = 60 / 0.15 / 100
•                                 K = 60 x 100 / 0.15
•                                K = 6000 / 0.15
•                               K = 40000 N / cm^2
