Regarding this, what is convective flow?
Convective transport (convective flow, bulk flow, convection) may refer to either heat or mass transfer. In the context of membranes, convective flow refers to the transport of fluid (pure solvent or solution) across a porous membrane, which is driven by the applied pressure.
One may also ask, what is a convection current and what causes it? Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.
Herein, what is convection with example?
Everyday Examples of Convection Boiling water - The heat passes from the burner into the pot, heating the water at the bottom. Ice melting - Heat moves to the ice from the air. This causes the melting from a solid to liquid. Hot air balloon - A heater inside the balloon heats the air and so the air moves upward.
What does a convection current look like?
Convection currents form because a heated fluid expands, becoming less dense. The less-dense heated fluid rises away from the heat source. As it rises, it pulls cooler fluid down to replace it. This fluid in turn is heated, rises and pulls down more cool fluid.
