The document is a presentation about fluid properties including density, specific weight, specific gravity, and specific volume. It defines each property, provides their mathematical relationships and units of measurement. Typical values are given for the density and specific weight of water and air. The presentation was created by Malik Hilal, Tuphail bhatt, and Junaid Pandith to explain these key fluid properties.

- 1. Ppt on properties of fluids Presented by:- Hilal Ahmad Malik Tuphail Bhatt Junaid Pandith
- 2. Fluid Properties Density Density of a fluid, , Definition: mass per unit volume, slightly affected by changes in temperature and pressure. = mass/volume = m/ Units: kg/m3 Typical values: Water = 1000 kg/m3; Air = 1.23 kg/m3 ppt by malik hilal ,tuphail bhatt,junaid pandith
- 3. Specific weight Specific weight of a fluid, Definition: weight of the fluid per unit volume Arising from the existence of a gravitational force The relationship and g can be found using the following: Since = m/ therefore = g Units: N/m3 Typical values: Water = 9814 N/m3; Air = 12.07 N/m3 ppt by malik hilal ,tuphail bhatt,junaid pandith
- 4. Specific gravity The specific gravity (or relative density) can be defined in two ways: Definition 1: A ratio of the density of a substance to the density of water at standard temperature (4C) and atmospheric pressure, or Definition 2: A ratio of the specific weight of a substance to the specific weight of water at standard temperature (4C) and atmospheric pressure. Unit: dimensionless. ppt by malik hilal ,tuphail bhatt,junaid pandith
- 5. Specific volume Specific volume of a fluid is defined as the volume of a fluid occupied by a unit mass or volume per unit mass of fluid is called specific volume Mathematically it is expressed as Specific volume= volume of fluid/mass of fluid =1/mass of fluid/volume=1/ ppt by malik hilal ,tuphail bhatt,junaid pandith
