What is Fluid Density? Specific Weight? Viscosity?

This is a lecture video on some of the most important properties of a fluid: Density, Specific Weight and Viscosity. You need to know and understand these properties in order to have any hope of understanding fluid flow analyses. Any Engineering students can find this video beneficial, but it is specifically directed towards undergraduate students of Mechanical Engineering who are studying Fluid Mechanics I. As a reference, students can refer to Munson's and Okiishi's book titled 'Fluid Mechanics' for further in-depth reading.
