Note that the pressure p is equal to minus the mean normal stress:[2] The motivation for doing this is that pressure is typically a variable of interest, and also this simplifies application to specific fluid families later on since the rightmost tensor in the equation above must be zero for a fluid at rest. Note that is traceless.
