Downward, Downriver, Downhill, the direction gravity pulls everything.
south is the direction that your veins flow
These are machines dealing with fluids, like (Axial Compressors, pumps and Fans). the term "Axial" is given due to the direction of inward and outward flow. In axial turbo machines the direction of outward flow is the same as the direction of the inward flow since the blades of the machines doesn't change the direction of flow.
because liqids can flow from higher level to lower level the gases flow in all available direction. due to this tendency of flowing,both of them called fluids

Valves - allow fluids or gases to only flow in one direction. They're control devices.
Fluids are substances that flow. Liquids flow, gases flow, and ionized gases (plasmas) flow. Thus, they are all fluids.
A check valve or one-way valve enables fluids to flow through in a single direction.
Fluids have the ability to flow. Fluids are Liquids and Gasses.
Flow
A fluid is any substance that can flow. Since liquids and both flow, they are fluids.
flow to
Fluids are substances that have the tendency to flow. Gases and liquids are both fluids because they both flow.
These terms are usually used in conjuction with fluid-fluid heat exchangers. In both cases, the two fluids in the exchanger are moving in parallel flowpaths with each other. In contraflow, the fluids move in opposite directions along those paths, so the two inlets are on opposite ends of the exchanger. In parallel flow, the fluids move in the same direction, so the inlets are on the same end.
