The dimensional formula for Reynold's number is

A

`["L"^(0)"M"^(0)"T"^(0)]`

B

`["LMT"]`

C

`["L"^(-1)"MT"]`

D

`["LMT"^(-1)]`

Text Solution

Verified by Experts

The correct Answer is:
A
Reynold's number describes the ratio of inertial force per unit area to viscous forcer per unit area for a flowing fluid.
Thus, Reynold's number is the ratio of two physical quantity of same dimension which cancel out each other. Hence, Reynold's number is dimensionless `["M"^(0)"L"^(0)"T"^(0)]` quantity.
