Mention any two limitations of dimensional analysis.

By Ritesh|Updated : November 9th, 2022

The limitations of dimensional analysis are - it is not possible to find the proportionality constant value and it is not possible to derive the formula having a logarithmic function, exponential function, and trigonometric function. A physical quantity's dimension is determined by how it relates to other physical quantities, such as its mass, length, and time.

Limitations of Dimensional Analysis

However, dimensional analysis has significant drawbacks, two of which are listed below.-

  • The proportionality constant's value cannot be calculated using this method.
  • The formula including the trigonometric, exponential, and logarithmic functions cannot be derived using this method.

Dimensional analysis is the study of the relationship between physical quantities using dimensions and units of measurement. Because it maintains the units' consistency, dimensional analysis is crucial for facilitating accurate mathematical computations.

Uses for Dimensional Analysis

Real-world physics uses dimensional analysis, which is a fundamental part of the measurement. We employ dimensional analysis for three key purposes:

  • To validate a dimensional equation's consistency
  • To determine how physical quantities in physical phenomena relate to one another
  • to convert units across different systems

Summary:

Mention any two limitations of dimensional analysis.

The inability to discover the proportionality constant value and to create a formula with a logarithmic function, exponential function, or trigonometric function are two of the limits of dimensional analysis. Dimensional analysis is a technique for determining the relationships between physical quantities by defining their dimensions.
