Question
Chapter 1, Problem 1.21P
Interpretation Introduction
Interpretation: The value of change in pressure required to reduce the given volume should be calculated.
Concept introduction: Bulk modulus of elasticity is defined as the ratio of differential change in pressure to the differential change in volume with respect to final volume (Volumetric Strain). It is the property of the material that characterizes compressibility.
The formula to calculate bulk modulus is,
Where,
dP is the differential change in pressure.
dV is the differential change in volume
V is the final volume.
