Question

The dimensions of the coefficient of viscosity are [ML^-1T^-1]. To convert to cgs unit poise to the MKS unit poiseuille the poise has to be multiplied by -

• A. $\frac{1}{10}$
• B. 10
• C. 10⁷
• D. 10⁹

Answer 1

n₁u₁ = n₂u₂ Let 1 poiseuille = n poise

1(kg. m^–1 s^–1) = n (gm. cm^–1. s^–1)

\ n = 10

i.e. 1 poiseuille = 10 poise
