Forced convection is when air ascends as a result of another force, such as the actions of fronts, orographic lifting, or converging wind. Free convection is caused by a factor such as intense heating of the Earth's surface, which warms air and causes it to rise.

What is difference between free and forced convection?
free convection : the transfer of heat resulting from differences in density of air, that thereby causes the flow of air. mechanical convection the transfer of heat resulting from a blower or fan that actively forces heated air throughout all areas
Convection always occurs in what two forms?
forced and natural convection possibly
An example of forced convection is the movement of hot air by a fan?
True
How does energy transfer in fans?
The energy transfer when a fan is used is known as forced convection.
What is a example of forced convection?
When air is forced to ascend because it has come into contact with a mountain or some other raised geographical feature, also called orographic lifting.
What is the Difference in normal convection and forced convection?
Forced convection is forced [man-made] and normal convection is natural.
What has the author Kotorynski written?
Kotorynski has written: 'Free and forced convection of heat in viscous flow' -- subject(s): Thermodynamics, Heat, Convection
What is difference between free and forced convection?
free convection : the transfer of heat resulting from differences in density of air, that thereby causes the flow of air. mechanical convection the transfer of heat resulting from a blower or fan that actively forces heated air throughout all areas
What are the applications of forced convection?
Forced convection are used in car radiators, cooling towers, air cooled heat exchangers etc.
Convection always occurs in what two forms?
forced and natural convection possibly
What provides forced convection?
velocity of fluid..
What is forced convection?
Convection caused by frontal or orographic lifting, or converging surface winds.
In a forced - air heating system the warm air circulates by convection?
No, its forced by an electric blower...otherwise it wouldn't be forced air
A forced air heater heats a house through?
convection
Are heat vents examples of forced or natural convection?
Natural
is the forced convection is the movement of hot air by a fan?
True
Which improves air circulation in forced air heating?
Convection
