Find the pressure necessary to change a volume of steel by

1.0 percent. Express the pressure in terms of atmospheric

pressure units 1 bar = 10°N/m², where bulk' modulus of

steel is 160 x 10' N/m².

160*10⁶ bar

Explanation:

Bulk modulus is defined as:

K = - V ΔP / ΔV

where V is the initial volume,

ΔP is the change in pressure,

and ΔV is the change in volume.

Given:

K = 160*10⁹ Pa

ΔV = - 0.01V

160*10⁹ Pa = - V ΔP / (-0.01V)

160*10⁹ Pa = ΔP / 0.01

ΔP = 160*10¹¹ Pa

ΔP = 160*10⁶ bar
