Fluids

Question 1

What’s pressure?

Answer 1

Distribution of force over an area (P=F/A)

Question 2

What’s hydrostatic pressure?

Answer 2

Pressure caused by the weight of fluid above an area

Question 3

Hydrostatic pressure is determined by

Answer 3

Depth and density I.e. P= pgz

P is density of fluid
g is acceleration due to gravity
z is depth in the fluid

Question 4

What’s byoyant force?

Answer 4

Net upward force in fluid that results from greater pressure on the bottom than top of an object

Question 5

Archimedes principle?

Answer 5

Buoyant force on an object is equal to the weight of the fluid the object displaces

Question 6

What’s pascals law?

Answer 6

A pressure applied to an incompressible fluid causes the same pressare increase throughout the fluid

Question 7

What is ideal gas?

Answer 7

Ideal gas = no volume = No intermolecular forces

Question 8

What does the boyle’s law imply?

Answer 8

Decreasing the volume of gas will increase the pressure of the gas by same factor

Question 9

Ideal gas law equation?

Answer 9

PV =nRT
