How Is Heat Transferred By Convection. Convection is the heat transfer due to the movement of a fluid such as a gas or liquid and carries heat energy away from the source of heat. Higher temperature fluid molecules expand the space they occupy.
Convection ovens can reduce cooking times by 25 or more compared with ordinary ovens. In convective heat transfer heat is transferred by diffusion conduction and by bulk fluid motion advection. When a substance is heated it causes its particles to.
The resulting heated space is.
The equation to calculate the rate of convection is as follows. Higher temperature fluid molecules expand the space they occupy. Thermal energy is transferred from hot places to cold places by convection. By evaporation and condensation c.
