MFE-Chap 3

Forces In Fluids

QuestionAnswer
force divided by area Pressure
the SI unit for pressure (Newton per square meter) pascal
a material that can eqasily flow fluid
an instrument used to measure barometric pressure barometer
acts in the direction opposite to the force of gravity, so it makes the object feel lighter buoyant force
states that the buoyant force acting on a submerged object is equal to the weight of the fluid the object displaces Archimedes' principle
mass divided by volume density
when force is applied to a confined fluid, the change in pressure is transmitted equally to all parts of the fluid Pascal's principle
multiples force by applying the force to a small surface area, the increase in pressure is then transmitted to another part of the contained fluid, which pushes on a larger surface area hydraulic system
states that as the speed of a moving fluid increases, the pressure within the fluid decreases Bernoulli's principle
an upward force lift

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:
