If 1 newton tangential force is required to maintain the velocity gradient of `1ms^(-1)`//m between two parallel layers of liquid each of area 1 sq m, the coefficient of viscosity of liquid is said to be…………

If a tangential force of 1dyne cm^-2 of the surface is required to maintain a relative velocity of 1cms^-1 between two layers of a liquid 1 cm apart, then the coefficient of viscosity of the liquid is said to be___.

The tangential forces per unit area of the liquid layer required to maintain unit velocity gradient is known as

When a liquid flows in a tube, there is relative motion between adjacent layers of the liquid. This force is called the viscous force which tends to oppose the relative motion between the layers of the liquid. Newton was the first person to study the factors that govern the viscous force in a liquid. According to Newton’s law of viscous flow, the magnitude of the viscous force on a certain layer of a liquid is given by F = - eta A (dv)/(dx) where A is the area of the layer (dv)/(dx) is the velocity gradient at the layer and eta is the coefficient of viscosity of the liquid. A river is 5 m deep. The velocity of water on its surface is 2 ms^(-1) If the coefficient of viscosity of water is 10 ^(-3 ) Nsm ^(-2) , the viscous force per unit area is :
