# Bulk Modulus Calculation

The calculator will calculate the bulk modulus or pressure or initial volume or change in volume as per selection from drop-down and given appropriate values. The Bulk Modulus is defined as the pressure increase needed to cause a given relative decrease in volume.

Bulk Modulus: B = P x V

_{i}/V_{c}; Pressure: P = B x V_{c}/V_{i}; Initial Volume: V_{i}= B x V_{c}/P; Change in Volume: V_{c}= P x V_{i}/B**where,**B = Bulk Modulus. p = Pressure, V_{i}= Initial Volume, V_{c}= Change in Volume.
