Slide 1 - Slide

Learning Outcomes
By the end of the lesson you will be able to:

  • define common fluid properties and;
  • solve problems related to the properties of fluids

Slide 2 - Slide

What fluid properties do you already know about?

Slide 3 - Mind map

Mass Density
Mass density is a way of measuring how much or matter is packed into a certain amount of space.



Slide 4 - Slide

Mass Density
In fluid mechanics, we talk about mass density to understand how tightly packed the particles in a liquid or gas are. We use this formula: 



  • Mass is how much matter is in an object (like how heavy something is).
  • Volume is how much space something takes up.
For example, water has a higher density than air because the particles in water are much closer together than the particles in air. That’s why water feels heavier and things can float on water but not in the air;
 Lower Density = FLOATS!







Density(ρ)=​Volume(V)​​Mass(m)​​

Slide 5 - Slide

Water at 4'C has a density of 1000 kg/m^3, which of the following would sink in water?
A
Air - 1.23 kg/m^3
B
Mercury - 13456 kg/m^3
C
Parrafin - 800 kg/m^3
D
Methanol - 791 kg/m^3

Slide 6 - Quiz

What is relative density? And what other name can it go by?

Slide 7 - Open question

If oil has a density of 800 kg/m^3, what is it's specific gravity?
