OnRamps Fluid Concepts

The rule that when force is applied to a confined fluid, the increase in pressure is transmitted equally throughout.

• pascal's principle
• bernoulli's principle
• archimedes' principle
• Newton's Law

A system that multiplies force by transmitting pressure from a small surface area through a confined fluid to a larger surface area.

• hydraulic system
• archimedes system
• pressure system
• bernoulli effect

What happens to pressure as you go deeper under water?

• it increases
• it decreases
• it stays the some
• no soup for you!

Fluids flow

• only when warmed up.
• from regions of low pressure to regions of high pressure.
• until evenly spread out.
• from high to low pressure.

The concept that air flows fast over the top of a curve wing than it does over the bottom and helps to create lift is

• Pascal's principle.
• Archimedes' principle.
• Bernoulli's principle.
• Newton's law

During a hurricane, the air outside a home moves much faster than the air inside the home. Which of the following is possible to happen?

• The windows can burst inward.

• The windows can burst outward.

• The windows cannot burst because the pressure inside and outside the home are equal.

• The windows cannot burst because the force inside and outside the home are equal.

Water flows through a pipe with different sized cross-sectional areas. Which section has the slowest fluid speed?

• I

• II

• III

• IV

Water flows in a horizontal pipe that is narrow but then widens. The pressure of the water moving in the pipe is

• greater in the wide part

• greater in the narrow part

• the same in both parts

To obtain the absolute pressure from the gauge pressure:

• subtract atmospheric pressure

• add atmospheric pressure

• subtract 273

• add 273

Archimedes' Principle states that... 

• The buoyant force acting on an object equals the volume of the fluid displaced by the object. 
• The buoyant force acting on an object equals the weight (force of gravity) of the fluid displaced by the object.
• The buoyant force acting on an object will always be equal.
