What will happen if the you place a smoke source near the hole?

If you place a smoke source near a hole, the smoke will likely flow into the hole due to differences in pressure or airflow. This can create a visual effect where smoke is drawn in, potentially indicating that the hole leads to a lower pressure area or a vacuum. Depending on the size and nature of the hole, the smoke might also exit from other openings, creating a flow pattern. Overall, this demonstration can illustrate principles of fluid dynamics and airflow.


What happens in a volcanic eruption?

The volcano will smoke and give off ash.Lava may flow out of the vent of the volcano.


How are humans affecting iguazu falls?

Humans are affecting Iguazu Falls through deforestation, pollution, and tourism activities. Deforestation can alter the water flow and ecosystem surrounding the falls, while pollution can harm the quality of the water. Tourism can lead to overcrowding and damage to the delicate environment of the falls.

Is a fall is faster than a flow?

there is a lot of difference between fall and flow... normally we use fall for the object moving without any support and in an angle nearer to 90 degree downwards.. whereas flow is moving with support nearer to 0 or 180 degree... Falling speed will be always according to law of gravity but flowing speed may vary which depends on the source of it... Example for fall: water fall Example for flow: slower than water fall : river flow faster than water fall : water coming out of fire engine

Which direction does the panama river flow?

It flows downwards. It flows downwards.


Why at a campfire the ash from the burning wood goes up into the air instead of downwards even though gravity causes things to fall downwards?

Because the tiny ash particles ride in the flow of hot air rising from the fire ... same as the smoke particles do.


Why are air conditioners are usually placed at a higher level rather than at a lower level?

Heat rises, cold falls. Hot air will rise towards the ceiling, while cold air will travel towards the floor. Thus, it's beneficial to have the air conditioning at a higher level to allow the cold air flow downwards.


How are waterfalls related to physics?

Gravity causes water to flow downwards.


Why does the person in the top floor will get less amount of water than the person in the ground floor when their taps are opened at the same time?

The person on the top floor will receive less water because they are against the force of gravity, which creates less pressure in the pipes. As water is pulled downwards, the pressure decreases with height. This results in a lower flow rate for the person on the top floor compared to the person on the ground floor.


What is responsible for stopping the downward flow of water?

Gravity is responsible for stopping the downward flow of water. As water flows downwards due to gravity, it eventually reaches a point where the force of gravity pulling it downward is balanced by other forces such as friction and surface tension, which prevent the water from continuing to flow downwards.


Why does a cloud of dry ice flow downwards?

It flows downwards because it is cold and cold air sinkse. The most important reason why it flows downwards is that dry ice is made of CO2 / carbon dioxide which = 1.5 times heavier than the air that we inhale.

What is the significance of laminar flow in the visualization of smoke movement?

Laminar flow is important in visualizing smoke movement because it creates smooth and predictable patterns, making it easier to track and analyze the flow of smoke. This helps researchers and engineers understand how smoke behaves in different environments, leading to better fire safety measures and ventilation systems.

What are examples of turbulent flow?

Smoke rising from a flame. At first the smoke rises with laminar flow before becoming turbulent just a few centimetres above the source.
