what is the limitations of dimensional analysis
Answers
Answer:
Limitations of dimensional method. Although dimensional analysis is very useful, it cannot lead us too far because of the following reasons:1.Dimensional method cannot be used to derive equations involving addition and substraction.
2..
Numerical constants having no dimensions cannot be obtained by method of dimensions.
Answer:-
★ Limitations of Dimensional Analysis:-
→ The value of the constant of proportionality cannot be determined.
→ If the constant of proportionality has dimensions and its nature is not known, dimensional analysis cannot be applied.
→ Dimensional analysis cannot be applied to relations involving trigonometric, logarithmic and exponential functions.
→ The relation connecting a set of physical quantities can be deduced only if the relation is in the form of a product.
→ If the number of quantities on which a physical quantity depends exceeds the number of fundamental units involved.
→ And, it is not possible to obtain an expression relating them.
