To expel hot air out of the kitchen, ‘A’ has an exhaust fan fitted on the window of her kitchen, and ‘B’ has a similar exhaust fan fitted on the wall near the ceiling of her kitchen. Which of the exhaust fan will expel the hot air more effectively? Explain why?
Answers
Answer:
B will expel hot air out of the kitchen most effectively.
Explanation:
Exhaust fans are generally fitted near the ceilings as the warm air rises up due to convection and easily goes out through the exhaust fans out of the kitchen and on the other hand exhaust fan fitted on window is very low so hot air rise up and became far from its reach so it will not able to to expel the hot air out effectively.
Answer:
The exhaust fan which is fitted near the ceiling of the kitchen will expel the hot air more effectively. Hot air rises up, so the exhaust which is fitted near the ceiling will be able to expel out hot air more effectively, as hot air will go straight upwards. In the exhaust which is located on the side, the air won't go directly through it.
