Question: Dimensions of coefficient of viscosity are...

Dimensions of coefficient of viscosity are

A

ML2T−2ML^{2}T^{- 2}

B

ML2T−1ML^{2}T^{- 1}

C

ML−1T−1ML^{- 1}T^{- 1}

D

MLTMLT

Answer

ML−1T−1ML^{- 1}T^{- 1}

Explanation

Solution

F=−η.Advdx⇒[η]=[ML−1T−1]F = - \eta.A\frac{dv}{dx} \Rightarrow \lbrack\eta\rbrack = \lbrack ML^{- 1}T^{- 1}\rbrack
