Expert Answer
Bulk modulus k is given by k = p/(ΔV/V) ...........(1)
where p is pressure, ΔV is change in volume and V is volume
if m is mass, we have density ρ = m/ V or log (ρ) = log(m) - log(V) .................(2)
since mass is constant, by differentiating (2), we get Δρ/ρ = -ΔV/V
Hence eqn.(1) is written as , k = p/ ( Δρ/ρ ) or p = k×( Δρ/ρ ) = k×0.001
