Adiabatic bulk modulus

The  Adiabatic Bulk Modulus calculator computes the bulk modulus as a function of the change in pressure and volume and the initial volume.  

INSTRUCTIONS: Choose units and enter the following:

• (dp)  This is the change in pressure.
• (dv) This is the change in volume
• (V) This is the initial volume.

Bulk Modulus: The bulk modulus is returned in units of pressure (kPa).  This can be automatically converted to other pressure units via the pull-down menu.

The Math

 
The isothermal bulk modulus  is the bulk modulus for a substance at constant temperature, defined by

               K_s=-V(dP/dV)_s

where

• K_s = bulk modulus
• P = pressure
• V = volume

dP/dV denotes the derivative of pressure with respect to volume
