here is your answer
The degree to which a fluid resists flow under an applied force,measure by the tangential friction force per unit area divide by the velocity gradient under condition of streamline flow . In other words , coefficient of viscosity of a liquid is a external force required to maintain unit velocity gradient between its two consecutive layers of unit surface area .
Dimension formula :- ML^-1 T^-1
