Fluid Dynamics Basics

What is the definition of a fluid?

• A fluid is a substance that has a fixed volume and cannot change shape.

• A fluid is a substance that has no fixed shape and can flow easily.

• A fluid is a substance that is solid and cannot flow.

• A fluid is a substance that has a fixed shape and cannot flow easily.

What are the three states of matter?

• energy

• plasma

• light

• solid, liquid, gas

What is viscosity?

• Viscosity is a measure of a fluid's temperature.

• Viscosity is a measure of a fluid's ability to flow easily.

• Viscosity is a measure of a fluid's color.

• Viscosity is a measure of a fluid's resistance to flow.

What is the equation for pressure?

• P = F*d

• P = F/V

• P = F*g

• P = F/A

What is Pascal's law?

• Pascal's law states that pressure decreases at every other point in the container when there is an increase in pressure at any point in a confined fluid.

• Pascal's law states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container.

• Pascal's law states that pressure remains constant at every point in the container when there is an increase in pressure at any point in a confined fluid.

• Pascal's law states that pressure increases at a different rate at every other point in the container when there is an increase in pressure at any point in a confined fluid.

What is the formula for calculating pressure in a fluid at a specific depth?

• pressure = density * gravity * depth

• pressure = density * depth / gravity

• pressure = density / gravity * depth

• pressure = density * gravity / depth

What is buoyancy?

• Upward force exerted by a fluid on an object

• The force that causes objects to sink in a fluid

• The force that keeps objects submerged in a fluid

• Downward force exerted by a fluid on an object

What is Archimedes' principle?

• Archimedes' principle states that when a body is partially or fully submerged in a fluid, it experiences a downward buoyant force equal to the weight of the fluid displaced by the body.

• Archimedes' principle states that when a body is partially or fully submerged in a fluid, it experiences no buoyant force.

• Archimedes' principle states that when a body is partially or fully submerged in a fluid, it experiences an upward buoyant force equal to the weight of the fluid displaced by the body.

• Archimedes' principle states that when a body is partially or fully submerged in a fluid, it experiences a sideways buoyant force.

What is the formula for calculating buoyant force?

• Buoyant force = Weight of the object submerged

• Buoyant force = Weight of the fluid displaced

• Buoyant force = Density of the fluid

• Buoyant force = Volume of the object

What is Bernoulli's principle?

• Bernoulli's principle states that as the speed of a fluid increases, its pressure increases.

• Bernoulli's principle states that as the speed of a fluid increases, its temperature decreases.

• Bernoulli's principle states that as the speed of a fluid decreases, its pressure increases.

• Bernoulli's principle states that as the speed of a fluid increases, its pressure decreases.
