WebPressure vs. Flow—The Basics. Pressure is force. It acts in all directions, all at once and with the same power. The amount of force a pressure exerts is directly related to the area in which the pressure is contained (pressure = force/area). Pressure does not require directional input, like a hammer on a nail. screwdriver phillips 00Web18 dec. 2024 · Pressure or flow pulsations can have negative consequences in some applications.
