Dimensional Formula of Reynolds Number (Re)

The physical quantity which helps determine the flow pattern of the liquid categorising it into a turbulent or laminar flow while it flows through a pipe. The ratio of inertial forces to viscous results in Reynolds number. The quantity is a dimensionless quantity. The laminar flow is termed as the type of flow in which […]

Dimensional Formula of Relative Density

A dimensional formula is a mathematical formula that represents a physical quantity in terms of fundamental quantities such as mass, length, and time. With the help of dimensional formulae, the fundamental quantities can be raised to different powers to build a new physical quantity. The powers of fundamental physical quantities are referred to as dimensions.

Dimensional Formula of Joule

In electronics and broad scientific applications, the joule is the standard unit of energy. A joule is the amount of energy expended when a force of one newton is applied across a one-meter displacement. One joule is equal to one watt of power wasted or emitted for one second. The heat was researched and its

Dimensional Formula of Intensity

The dimensions of a physical quantity are the powers to which the basic quantities are elevated to represent that amount. The dimensional formula of any physical quantity is an equation that explains how and which of the base quantities are contained in that amount. It is written by enclosing the symbols representing base amounts in

Dimensional Formula of Impulse

An impulse is a huge force that acts in a short period with finite momentum. We see impulse in our day-to-day activities; when we break a wooden piece with an axe with so much force, it breaks immediately, right? This is a classic example of impulse. We can find impulse by using the formula, impulse

Dimensional Formula of Coefficient Of Elasticity

The coefficient of elasticity or modulus of elasticity is the measurement of the elastic property of a material. When a force is applied to a material, its extent of getting distorted varies from material to material. This constant gives an idea about the degree of distortion. Elasticity is represented using δ.  Dimensional Formula The dimensional

Dimensional Formula of Angular Speed

Angular speed is defined as the rate of change of angular distance (i.e., ⍵=  θ/T). Usually measured in radian per seconds. Dimensions – these are mathematical measurements for a particular quantity or measure. These give a simplified understanding of the quantity we are measuring. We use many objects in our everyday life. They all have

Dimensional Formula of a Light Year

One light-year is defined as the distance a light beam travels in a year. It is used to communicate galactic distances. It is almost equal to 6 trillion miles (9.7 trillion km). According to the International Astronomical Union, a light-year is a distance travelled by light in a Julian year. The light-year unit first appeared
