It is transmitted equally in all directions throughout an incompressible fluid.
The Darcy-Weisbach equation describes the frictional decrease in this quantity. One form of this quantity is given by the power flux density over c, and scales with the fourth power of temperature. The Poiseuille equation gives the difference in this quantity in terms of flow rate and pipe radius. It is transmitted equally in all directions throughout an incompressible fluid. Increasing the speed of a fluid decreases this quantity, according to Bernoulli's principle. It is measured in units of torr, pascals, or standard atmospheres. For 10 points, name this physical quantity defined as force per unit area.
