Define Capillarity: Define Capillarity is a phenomenon of rise or fall of liquid surface relative to the adjacent general level of liquid. This phenomenon is due to the combined effect of cohesion and adhesion of…
Surface Tension: Surface Tension - Due to molecular attraction, liquids have properties of cohesion and adhesion. Cohesion is due to the force of attraction between molecules of same liquid. Otherwise, the intermolecular attraction holds the…
Viscosity Unit: Viscosity Unit is the property of a fluid which determines the amount of resistance to a shearing stress. A real fluid has no viscosity but it is nonexistent. Viscosity can also be defined…
Properties of Fluid in Fluid Mechanics: The following properties of fluids are of general importance to the study of fluid mechanics. Mass density (ρ) Specific Volume (v) Specific weight (w) Specific gravity (S) 1. Mass…
Classification of Fluids: Classification of Fluids are as follows. Ideal fluids and Real or Practical fluids. Newtonian fluids and Non-Newtonian fluids. 1 .Ideal Fluids: Ideal fluids are having following properties. It is incompressible. It has zero…
Types of Unit System: All physical quantities are measured in certain units. There are two Types of Unit System, namely: Fundamental units Derived units Fundamental Units: All the physical quantities arc expressed of the following…
