In fluid mechanics, the pressure-gradient force is the force that results when there is a difference in pressure across a surface. In general, a pressure is a force per unit area, across a surface. A difference in pressure across a surface then implies a difference in force, which can result in an acceleration according to Newton's second law of motion, if there is no additional force to balance it. The resulting force is always directed from the region of higher-pressure to the region of lowe… WebMar 27, 2024 · Pressure gradient definition: the change of pressure per unit distance Meaning, pronunciation, translations and examples forest school log circle
