The dimensional formula for Reynold's number is

Options

A. `[L^(0) M^(0) T^(0)]`
B. `[L^(1) M^(1) T^(1)]`
C. `[L^(-1) M^(1) T^(1)]`
D. `[L^(1) M^(1) T^(-1)]`

Answer

A

Explanation

Reynold's number describes the ratio of inertial force per unit area to viscous force per unit area for a flowering fluid
Thus , Reynold's number is the ratio of two physical quantity of same dimensions which cancel out each other . Hence Reynold's number is dimensions quantity
