Finally, " p ik " is the fluid-pressure tensor expressed in the local moving coordinate system
2.
The integral energy stored in the quantum pressure tensor is proportional to the Fisher information, which accounts for the quality of measurements.
3.
The negative of the stress tensor is sometimes called the pressure tensor, but in the following, the term " pressure " will refer only to the scalar pressure.
4.
Any situation in which this last term is zero will result in the total pressure tensor being symmetric, and the conservation of angular momentum equation will be redundant with the conservation of linear momentum.

6.
If, however, the internal rotational degrees of freedom of the particles are coupled to the flow ( via the velocity term in the above equation ), then the total pressure tensor will not be symmetric, with its antisymmetric component describing the rate of angular momentum exchange between the flow and the particle rotation.
