scalar pressure मीनिंग इन हिंदी

These are basically vector control volumes different from the scalar pressure control volumes and different from each other.
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.
This expression separates the stress into a scalar part on the left which may be associated with a scalar pressure, and a traceless part on the right which may be associated with shear forces.
