Define Capillarity

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 liquid particle. The rise of liquid level is known as Capillary Rise whereas the fall of liquid surface is known …

Surface Tension

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 liquid molecules together is known as cohesion. This force is very small. It enables the liquid to withstand a small tensile …

Viscosity Unit

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 as the property of a fluid due to which it offers resistance to the movement of one layer of fluid …

Classification of Fluids

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 viscosity. Shear force is zero when the fluid is in motion i.e. No resistance is offered to the motion of …

Types of Unit System

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 three fundamental Types of Unit System: Length (L) Mass (M) Time (T) Derived Units: Some units called derived units are …
