The direction of flow is always from what to what?

Explanation:
Flow follows a pressure gradient: fluid moves from regions of higher pressure toward regions of lower pressure because that pressure difference provides the driving force. In a hydraulic system, a pump creates high pressure on the supply side and the fluid flows through the circuit toward components where the pressure is lower, doing work along the way. If pressures are equal, there’s no net flow. Only with external energy can flow be driven from low to high pressure, but in normal passive flow the direction is from high to low pressure.
