# Volume Differential

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Volume differential, abbreviated as $$\Delta V$$, is the difference between an expanded or reduced volume of a liquid.

## Volume differential formula

 $$\large{ \Delta V = V_f - V_i }$$

### Where:

 Units English Metric $$\large{ \Delta V }$$ = volume differential $$\large{ in^3 }$$ $$\large{ mm^2 }$$ $$\large{ V_f }$$ = final volume $$\large{ in^3 }$$ $$\large{ mm^2 }$$ $$\large{ V_i }$$ = initial volume $$\large{ in^3 }$$ $$\large{ mm^2 }$$

## Related Volume Differential formula

 $$\large{ \Delta V = \frac {p \; V_i}{ K} }$$ (Bulk Modulus)

### Where:

$$\large{ \Delta V }$$ = volume differential

$$\large{ K }$$ = bulk modulus

$$\large{ V_i }$$ = initial volume

$$\large{ p }$$ = pressure
