Bernoullis principle states that the faster a fluid moves the less pressure the fluid exerts?
Yes, Bernoulli's principle states that as the speed of a fluid increases, the pressure exerted by the fluid decreases. This principle is based on the conservation of energy in a flowing fluid. It is commonly observed in applications such as airplane wings, where faster-moving air creates lower pressure and generates lift.
When speed increases why does drag increase?
As an object moves faster through a fluid (like air or water), it creates more turbulence and pressure differences around it, leading to increased drag force. This drag force is caused by the friction and resistance that the fluid exerts on the moving object, which increases as the speed increases.
What happens to fluid pressure when a fluid moves?
When a fluid moves, the fluid pressure decreases. This is due to the conservation of energy principle, where the kinetic energy of the moving fluid is converted from the pressure energy of the fluid. The pressure decreases as the fluid gains velocity.
What is the definition of divergence pressure?
Divergence pressure refers to the decrease in pressure experienced by a fluid as it moves faster through a constriction or narrowing in a pipe or channel. It is caused by the conversion of kinetic energy to pressure energy when fluid velocity increases.
What is the factor described by Bernoulli's principle that allows airplanes to fly?
The faster a fluid travels the less pressure it exerts. Since the fluid (air) is traveling slower beneath the wing than the air going over the top, lift is created.

How do you calculate satic pressure?
Static pressure is typically calculated using the formula P = ρgh, where P represents static pressure, ρ is the fluid density, g is the acceleration due to gravity, and h is the height of the fluid column or the depth below the surface. This formula assumes that the fluid is incompressible and that there are no velocity effects present.
Explain in detail what Bernoullis Principle is?
Bernoulli's principle states that as the speed of a fluid increases, its pressure decreases, and vice versa. This principle is based on the conservation of energy in a fluid flow, where the sum of kinetic energy, potential energy, and pressure energy remains constant. It is commonly used to explain how airplane wings generate lift, where the flow of air over the wing creates a pressure difference that lifts the aircraft.
What is the movement of fluid down a pressure gardient called?
The movement of fluid down a pressure gradient is called flow. It occurs when a fluid moves from an area of high pressure to an area of low pressure in order to equalize the pressure difference.
If the air moves faster below an object does pressure push the object upward or downward?
If the air moves faster below an object, the pressure is lower compared to the pressure above the object. This pressure difference creates lift, causing the object to be pushed upwards.
When an object is moving faster through a fluid -how does this affect the force of friction?
When an object moves faster through a fluid, it experiences an increase in the force of friction due to the higher velocity leading to greater resistance from the fluid. This is because the faster movement creates more turbulence and pressure on the object's surface, resulting in an increase in friction.
What effect does cold air have on air pressure?
Cold air is denser than warm air, so it exerts a higher pressure. When cold air moves into an area, it can increase the air pressure in that location. Conversely, when warm air moves into an area, it can decrease the air pressure.
Why is pressure low under a train?
Pressure underneath a moving train is lower because of the Bernoulli's principle, which states that as fluid (such as air) moves faster, its pressure decreases. The train's movement creates airflow beneath it, causing the pressure to drop.
