Give eqn. for uniformly dense fluid escaping a hole at the bottom of a barrel
|
V=(2gh)^(1/2)
|
|
|
Eqn. for gauge pressure Pg at depth d
|
Pg=(density)(gravity)(depth)
|
|
|
Define pressure in terms of Force
what the units of Pascals are |
P=F/A
force per area hence measured at Pascal=N/m^2 |
|
|
Archimedes' Principle
Give Eqn for % of an object floating |
The ratio of object:fluid density is equal to % object submerged
Therefore % floating is 1-% submerged. BEWARE TRICK QUESTIONS WITH FLOATING AND SUBMERGED USAGE |
|
|
For fluids, sound travels faster in dense fluids, T/F?
|
False, less molecules means sounds can travel faster. Does not apply to solids
|
|
|
Give Bernoulli's principle
|
Bernoulli's principle
|
|
|
Give fluid continuity eqn.
|
A1*V1=A2*V2
Area*flow rate is constant for fluid |
