Question

Compute the fractional change in volume of a glass slab, when subjected to a hydraulic pressure of 10 atm.

Answer 1

The applied hydraulic pressure is 10 atm and the bulk modulus of glass is 37× 10 9  N/ m 2 .

The bulk modulus of glass is given by the equation,

β= Δp ΔV V ΔV V = Δp β

Substituting the values in the above expression, we get:

ΔV V = 10 atm× 1.013× 10 5  Pa 1 atm 37× 10 9  N/ m 2 ≈0.0027

Hence, the fractional change in the glass slab is 0.0027.
