What happens to the atmospheric pressure as elevation increases?
The higher the altitude, the lower the pressure becomes. One way to think of this is that the lower levels of the atmosphere, near the surface, are being pressed down by the molecules stacked above them, all of them drawn by Earth's gravity. Similarly, water in the oceans exerts a higher pressure the deeper you dive. Also, at the higher levels of the atmosphere, it is easier for molecules of lighter gases to achieve enough velocity to fly off into space.
What increases as a rock falls to the ground?
As a rock falls to the ground, its kinetic energy increases due to its increasing velocity towards the Earth's surface. The rock's potential energy decreases as it loses height and moves closer to the ground. Additionally, the rock's acceleration due to gravity increases as it falls, leading to an increase in its overall speed and momentum.
How does the slope of the stream affected erosion and deposition?
A steeper slope in a stream increases the velocity of the water, leading to increased erosion of sediment and rocks. This results in greater transportation of material downstream. Conversely, a gentler slope decreases the velocity of the water, causing less erosion and more deposition of sediment.
What generally happens to atmospheric pressure on a windy day?
On a windy day atmospheric pressure decreases because the higher the wind velocity, the lower the air pressure, or atmospheric pressure. This is how chimneys work, the air that moves above the chimney causes low air pressure because of the high wind velocity compared the velocity of the air inside a house. The air inside the house goes towards the low air pressure and takes the smoke with it.
What is stagnation pressure?
Static pressure is the pressure exerted by fluid in all directions, when it is in rest. Stagnation pressure is the sum of static and dynamic pressure of fluid in motion. Dynamic head is given by (velocity)^2/2*g.
How does pressure change with variations in flow rate?
Pressure changes with variations in flow rate in a direct relationship. As flow rate increases, pressure decreases, and as flow rate decreases, pressure increases. This is known as the Bernoulli principle, which states that as fluid velocity increases, its pressure decreases.
What is the effect on velocity and pressure if a liquid flows in a convergent pipe?
I think velocity is directly proportionate to its applying pressure.
What is the relationship between flow rate pressure?
With the increase in flow rate the velocity of the fluid increases. and with the increase in velocity the pressure decreases, because there will be pressure drop (Refer Bernoulli's Theorm). So with increase in Flow rate the pressure decreases.
What as a speed increases its pressure decresec?
As the speed of a fluid increases, its pressure decreases according to Bernoulli's principle. This is because the increase in velocity leads to a decrease in static pressure, as the kinetic energy of the fluid increases.
What According to Bernoulli's principle what characteristics of a moving fluid determines its pressure?
speed
What do you mean by weather change?
atmospheric pressure increases atmospheric pressure decreases wind velocity increases wind velocity decreases rain begins to fall rain stops snowfall or other precipitation begins precipitation ends cold front comes in warm front comes in
When the speed of a fluid increases the pressure decreases when speed of a fluid decreases the pressure increases is called?
This is known as Bernoulli's principle, which states that an increase in the speed of a fluid is accompanied by a decrease in pressure, and vice versa. It explains the relationship between velocity and pressure in a moving fluid.
What happens to the velocity as the height increases?
As height increases, the velocity generally decreases due to the effect of gravity. This is because potential energy increases while kinetic energy decreases, resulting in a slower velocity.
When balloon ascends its velocity decreases?
no it increases
What describes the relationship between the velocity and pressure of a fluid?
In a fluid, the velocity and pressure are related by Bernoulli's principle, which states that as the velocity of a fluid increases, its pressure decreases, and vice versa. This relationship is often seen in applications such as fluid dynamics and aerodynamics.
Air diffuser defition?
It increases the pressure of the down-steaming air while its velocity decreases due to the convert of the kinetic energy into pressure energy
Why the pressure of fluid decreases as area of pipe decreases?
The pressure of a fluid decreases as the area of a pipe decreases due to the principle of continuity. When fluid flows through a pipe, its volume flow rate remains constant, so as the area decreases, the fluid has to move faster to maintain the same flow rate, which reduces the pressure. This is described by Bernoulli's equation, which relates the pressure, velocity, and elevation of a fluid.
