General Behavior Weight Weight of a quantity of fluid is  W = mg   Where: m   = mass (kg) g     = standard earth gravity  = 9.81 m /s 2  or 32.174 ft/s 2 Unit in kg m / s 2  or Newton (N)
General Behavior Mass (m) Defined as the amount of matter in an  object.  Unit : kg

General Behavior Density ( ρ ) The quantity of matter contained in a unit  volume of the substance.  Unit: kg /m 3 - Density of liquid is nearly constant - Density of water = 998 kg / m 3 v m volume mass = = ρ
General Behavior - Density is highly variable in gases and is a  function of the gas composition, its  temperature and its pressure. Where: P = pressure T = temperature R = gas constant RT P = ρ

General Behavior Specific Gravity (SG) Ratio of a fluid density to a standard  reference fluid, water (for liquid) and air  (for gases). Unit : None 3 / 1000 m kg SG liquid water liquid liquid ρ ρ ρ = = 3 / 205 . 1 m kg SG gas air gas gas ρ ρ ρ = =
General Behavior Example: What is the specific gravity of mercury if  ρ   HG  = 13 580 kg / m ?

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
