pressure force pressure force[′presh·ər ‚fȯrs] (fluid mechanics) The force due to differences of pressure within a fluid mass; the (vector) force per unit volume is equal to the pressure gradient -∇ p, and the force per unit mass (specific force) is equal to the product of the volume force and the specific volume -α∇ p.
