Bulk Modulus an overview ScienceDirect Topics
网页Bulk modulusis the measure of the decrease in volume with an increase in pressure. The “modulus of elasticity” of a liquid varies widely, depending on the specific gravity and temperature of the liquid. Typical values are less than 30,000 psi to greater than 300,000 psi, depending upon the liquid.
