Downward, Downriver, Downhill, the direction gravity pulls everything.
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.
A steady stream like movement of matter in one direction is called a flow. This can refer to the flow of fluids like water or air, or the movement of particles in a specific direction. This movement can be continuous and can vary in speed and intensity.
A fluid is any substance that can flow. Since liquids and both flow, they are fluids.
Winds are named for the direction they flow from. For example, a northeast wind comes from the northeast direction.
Viscosity is a fluid's resistance to flow. It is a measure of the fluid's internal friction and is influenced by the fluid's composition and temperature. Fluids with high viscosity flow more slowly than fluids with low viscosity.
Friction between fluids is caused by the interaction of molecules within the fluid. This friction can slow down the flow of the fluids, making it more difficult for them to move smoothly. It can also create turbulence and resistance, which can further impede the flow of the fluids.
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.
The viscosity modulus is a measure of a fluid's resistance to flow. It is related to the flow behavior of fluids because fluids with higher viscosity moduli flow more slowly and are more resistant to deformation. In general, fluids with higher viscosity moduli exhibit more viscous behavior, while fluids with lower viscosity moduli flow more easily and exhibit less viscous behavior.
