Why is air pressure at the top of the chimney lesson than air pressure at the bottom?
Air pressure at the top of a chimney is lower than at the bottom due to the principles of buoyancy and the stack effect. As warm air rises, it expands and becomes less dense, creating lower pressure at the top compared to the cooler, denser air at the bottom. This difference in pressure encourages the upward flow of air and gases, which is essential for efficient ventilation and combustion in systems like fireplaces or furnaces.

Why liquid rushes faster at the bottom hole than the tops?
The liquid rushes faster at the bottom hole because of the effects of gravity. The pressure at the bottom hole is higher due to the weight of the liquid above it, causing it to flow faster. Buoyancy effects also play a role in the flow dynamics.
Is air pressure at the bottom of thr grand canyon high or low?
The air pressure at the bottom of the Grand Canyon is higher than at the rim due to the weight of the air above it compressing the air molecules. This can make it feel hotter and more humid at the bottom compared to the top.
How does the water pressure change at each level in a jug?
In a jug, the water pressure increases with depth due to the weight of the water above exerting force. The pressure at the bottom of the jug is higher than at the top. This pressure difference is the reason why water squirts out with more force from a spout at the bottom than at the top.
What is diatolic pressure?
Diastolic pressure is the bottom number in a blood pressure reading, indicating the pressure in the arteries when the heart is at rest between beats. It represents the minimum pressure in the arteries during the cardiac cycle. A normal diastolic pressure is typically less than 80 mmHg.
Why will water at the bottom of a geyser not boil when it as at 100?
Water only boils at 100 degrees ( in C ) when the pressure on it is standard atmospheric pressure. In Denver, it boils at a lower temperature, and in a pressure cooker, it can get a lot hotter than that and still not boil. At the bottom of a geyser, the pressure is more than atmospheric pressure because of all the water laying on top of the lowest layer, so it can go higher than 100 without boiling.
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 bottom width is greater than the top width of chimney?
so that the smoke is concentrated upwards
Should you block your chimney at the top or bottom?
You should block your chimney at the top rather than the bottom. Blocking it at the top helps prevent rain, debris, and animals from entering the flue while allowing for proper ventilation. This approach also reduces the risk of moisture damage and keeps the chimney more secure. Additionally, it helps maintain airflow, which is important for preventing dangerous gases from accumulating.
When the pressure at the bottom of a submerged object is less than the pressure at the top of the submerged object a buoyant force is produced.?
greater than
Why are dams built stronger and broader at the bottom?
Because water pressure is more intense at depth than it is near the surface - hence the dam has to be stronger at the bottom - it withstands more pressure at the bottom.
What is fallout from the chimney?
if it's the game it doesn't make any sense. if you mean fall out of a chimney than that's when you fall out of a chimney.
Is there more pressure at the bottom of a bathtub of water 30cm deep or at a bottom of a pitcher of water 35cm deep?
The pressure at the bottom of the pitcher of water 35cm deep is higher than at the bottom of the bathtub of water 30cm deep. Pressure in a fluid increases with depth, so the deeper the water column, the greater the pressure at the bottom. This is due to the weight of the water above exerting a force on the bottom.
Why is there more pressure at the bottom of the pool than at the top?
More water on TOP of you.
Why does the bottom of a airplanes wing have high air pressure?
Because the air moving above the wing is of lower pressure than the bottom. This pressure differential is what creates lift. Check out Bernoulli's Principle for more information.
Why dams must be constructed so that they are much thicker at the bottom than the top?
Because the water pressure at the bottom of the dam is much more than the top.
