A property of Thermodynamic system measuring a change of internal energy
U with respect to the change of its volume
V:
(1) | p = - \left( \frac{\partial U}{\partial V} \right)_{S, N} |
with entropy S and number of particles N being constant.
It is related to mechanical pressure and measures in the same units:
Symbol | Dimension | SI units | Oil metric units | Oil field units | Additional |
---|---|---|---|---|---|
p | Pa |
