What is the formula of bulk modulus of elasticity…
It is given by the ratio of pressure applied to the corresponding relative decrease in volume of the material. The relation is given below.
B = ΔP /(ΔV/V)
B: Bulk modulus
ΔP: change of the pressure or force applied per unit area on the material
ΔV: change of the volume of the material due to the compression
V: Initial volume of the material in the units of in the English system and N/m2 in the metric system.
