what principle is used by exhaust fan

Answers

Answered by linasunil85

Answer:

Exhaust fans work by sucking hot or humid air out of a small, localised area, allowing fresh air to enter from elsewhere (perhaps a doorway or vent) in order to replace it. The warm air that's drawn out using an exhaust fan is then pulled through a ducting system and expelled outside.

please give me brainliest answer please please please

Answered by varshikavyas

hot air rises up that's why it is set up at the top. secondly for movement their must be a change in concentration this is done by the exhaust fans and hence the hot, dusty,humid air rusgea out.
