According to Pascal’s Principle, how is applied pressure transmitted to every point in a fluid and to the walls of the container holding the fluid? a. Pressure decreases toward the container walls. b. Pressure increases toward the container walls. c. Pressure is equal and uniform throughout the fluid. d. Pressure depends on the shape of the container

Moving fluids can exhibit __________ flow or turbulent flow.
What is laminar (smooth)
100
He developed this principle: Fb = Fg (displaced fluid) = mfg magnitude of buoyant force = weight of fluid displaced

Which of the following statements does not describe an ideal fluid? 

a. An ideal fluid is incompressible.

 b. An ideal fluid has internal friction (viscosity).

 c. The flow of an ideal fluid is always steady. 

d. The flow of an ideal fluid is always laminar.

b.

The pressure in a fluid decreases as the fluid's velocity increases.
What is Bernoulli's Principle
200

He developed this principle: Pressure applied to a fluid in a closed container is transmitted equally to every point of the fluid and to the walls of the container.

If you've ever rested an air mattress in a swimming pool, you have experienced this.
What is buoyant force.
300
This is a measure of how much force is applied over a given area.
What is pressure.
300

This type of fluid is incompressible, nonviscous, and, when undergoing steady flow, nonturbulent.
