Fluid Dynamics

What happens to water pressure as depth increases?

• Water pressure decreases as depth increases.

• Water pressure remains constant regardless of depth.

• Water pressure increases as depth increases.

• Water pressure fluctuates randomly with depth.

How does pressure difference affect fluid movement?

• Pressure difference has no effect on fluid movement.

• Fluid moves from low to high pressure areas.

• Pressure difference causes fluid to flow from high to low pressure areas.

• Fluid movement is only influenced by temperature changes.

What role does mass play in fluid pressure?

• Fluid pressure is only determined by temperature.

• Mass decreases fluid pressure regardless of depth.

• Mass has no effect on fluid pressure.

• Mass affects fluid pressure by determining the weight of the fluid column above a point, influencing the pressure at that depth.

Can you explain the relationship between volume and pressure in fluids?

• Increasing volume always leads to a decrease in pressure in fluids.

• Pressure remains constant regardless of changes in volume in fluids.

• Volume and pressure are inversely related in fluids; as volume decreases, pressure increases.

• Volume and pressure are directly related in fluids; as volume increases, pressure increases.

How does the shape of a container influence fluid pressure?

• The shape of the container has no effect on fluid pressure.

• Fluid pressure is uniform regardless of container shape.

• The shape of the container can affect the distribution of pressure within the fluid.

• Fluid pressure only depends on the volume of the fluid, not the shape of the container.

How does the viscosity of a fluid affect its flow rate?

• Higher viscosity leads to a faster flow rate.

• Viscosity has no effect on flow rate.

• Higher viscosity results in a slower flow rate.

• Viscosity only affects the temperature of the fluid.

How does temperature affect the viscosity of a fluid?

• Higher temperatures increase fluid viscosity.

• Temperature has no effect on viscosity.

• Higher temperatures decrease fluid viscosity.

• Viscosity is only affected by pressure, not temperature.

What happens to the flow of a fluid when it encounters an obstacle?

• The fluid flows around the obstacle without any change.

• The fluid stops completely at the obstacle.

• The flow of the fluid is disrupted and may change direction.

• The fluid flows faster past the obstacle.

How does the depth of a fluid affect the pressure experienced at the bottom?

• Pressure increases with depth due to the weight of the fluid above.

• Pressure decreases with depth due to the weight of the fluid above.

• Pressure remains constant regardless of depth.

• Pressure fluctuates randomly with depth.

What is the pressure exerted by 10 m of water?

• 100000 Pa

• 98100 Pa

• 50000 Pa

• 98000 Pa
