# The dimensions of the coefficient of viscosity are :

$ML^{-1}T^{-1}$

##### SOLUTION
Equation : $F=-\eta Adv/dz$
F=force, A=area,
$\eta$= coefficient of viscosity,
$dv$ is change in velocity when distance change by $dz$

$\left[ \eta \right] =\dfrac { \left[ F \right] \left[ dz \right] }{ \left[ A \right] \left[ dv \right] } =\dfrac { \left[ ML{ T }^{ -2 } \right] \left[ L \right] }{ \left[ { L }^{ 2 } \right] \left[ L{ T }^{ -1 } \right] }$

$\left[ \eta \right] =\left[ M{ L }^{ -1 }{ T }^{ -1 } \right]$
