Explain this phenomena when a fireplace smoke rises up the chimney faster when wind is blowing outside?
Bernoulli's principle - the pressure on the top of the chimney would decrease, due to the speed of the air.Bernoulli's principle - the pressure on the top of the chimney would decrease, due to the speed of the air.Bernoulli's principle - the pressure on the top of the chimney would decrease, due to the speed of the air.Bernoulli's principle - the pressure on the top of the chimney would decrease, due to the speed of the air.
How do changes in temperature of air affect its density?
As temperature increases, air density decreases because the air molecules have more energy and spread out, causing the air to become less dense. Conversely, as temperature decreases, air density increases because the air molecules have less energy and come closer together, making the air more dense.
Is density of the air greater higher or lower?
The density of air decreases as altitude increases. At higher altitudes, the air molecules are more spread out, resulting in lower air density compared to sea level.
What do air density and air pressure have in common?
Air density and air pressure are both properties of the atmosphere that are related to each other. As air density increases, air molecules are packed more closely together, which also leads to an increase in air pressure. Conversely, as air density decreases, air pressure decreases as well.
How does increasing attitude affect air pressure and density?
as the altitude increase, the effect of gravity become more insignificant on air and the air become more disperse or thinner hence it does affect the air pressure and density by decreasing both air pressure and density of the air.
What are the benefits of installing a chimney exhaust fan in your home?
Installing a chimney exhaust fan in your home can help improve air quality by removing smoke, odors, and pollutants from your living space. It can also enhance the efficiency of your fireplace or stove by increasing the draft, which leads to better combustion and reduced creosote buildup. Additionally, a chimney exhaust fan can help prevent backdrafts and downdrafts, ensuring that your fireplace or stove operates safely and effectively.
Why do cars have a exhaust?
The same reason a home fireplace needs a chimney. Cars burn fuel and air. The byproduct of this is exhaust gas. The exhaust gas needs to be expelled somewhere so it is piped out under the vehicle to the back where nobody will be breathing it.
Why is air pressure at the top of a chimney less than air pressure at the bottom?
Smoke rises up the chimney partly because hot air rises and partly because it is pushed wind blowing across the top of a chimney lowers the air pressure there the higher pressure at the bottom pushes air and smoke up the chimney
Why higher density air is better for combustion?
The higher the air density, the more oxygen available for combustion.
How do differences in air pressure help smoke to rise up a chimney?
Differences in air pressure create a pressure gradient that causes air to move from high pressure areas to low pressure areas. When the air inside the chimney is heated by the fire, it becomes less dense and rises. This creates a lower pressure inside the chimney relative to the outside air, which causes the smoke to be drawn up and out of the chimney.
Why is air pressure at the top of the chimney less than air pressure at the bottom?
Smoke rises up the chimney partly because hot air rises and partly because it is pushed wind blowing across the top of a chimney lowers the air pressure there the higher pressure at the bottom pushes air and smoke up the chimney
When you compare the density of water or air with another object how can you tell which has the lower or higher density?
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
How does a chimney work using convenction?
A chimney works by creating a temperature difference between the air inside and outside the chimney. When the fire heats the air inside the chimney, it becomes less dense and rises, pulling in fresh air to feed the fire. This convection process helps draw smoke and gases up and out of the chimney.
How do differences in air pressure cause smoke to rise up a chimney?
Differences in air pressure cause air to flow from areas of high pressure to low pressure. In a chimney, the warm air from the fire creates a lower pressure inside the chimney relative to the outside, causing the smoke to rise up and out of the chimney.
Will duel exhaust increase gas mileage for a 2007 Nissan Titan?
No it will not. If you have more air exhaust going out you have more air/fuel coming in thus more power but less fuel economy. Its a trade off.
Why do the cornish tin mine chimney stacks have brick at the top half and not stone like the rest of the construction?
The top of the chimney was made from brick because this would heat up faster than stone, and if the top of the chimney is hotter than the rest of the chimney then the draught of air rising up the chimney would increase, therefore making the chimney more efficient.
How does air density affect flight?
The more dense the air, the more lift is available for a wing. A properly shaped wing takes full advantage of normal air density.
