To determine the unit of viscosity of liquids, we can follow these steps: ### Step 1: Understand Viscosity Viscosity is defined as the resistance of a liquid to flow. It quantifies how much a fluid resists deformation or flow when a force is applied. **Hint:** Remember that viscosity relates to how "thick" or "thin" a liquid is in terms of flow. ### Step 2: Formula for Viscosity ...

Define coeffiecient of viscosity of a liquid. Write down its dimensional formula and MKS unit.

The coefficient of viscosity of a liquid of sigma = 1.0 CGS units as determined by measuring the terminal velocity of a spherical solid ball of density p= 1.5 CGS units inside the liquid. If the ball of radius 1.00cm attain terminal velocity 1cm/s, then the viscosity (in CGS units) of the liquid as calculated from the observations of the experimental is: [Take g=10m//s^(2) ]

Complete the following sentences: (a) Pressure at a depth h in a liquid of density rho is …...... (b) Pressure is …... In all direction about a point in a liquid. (c ) Pressure at all points at the same depth is …. (d) Pressure at a point inside a liquid is ....... to its depth. (e ) Pressure of a liquid at a given depth is ....... to the density of liquid.

In case of a liquid

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 :

Pressure exerted by a liquid is ..................... proportional to the density of liquid.

An external force 6N is applied on a sphere of radius R = 10 cm of mass 1 kg and the sphere moves in a liquid with a constant velocity 5 m/s making 530 with the horizontal.The coefficient of viscosity of the liquid is 20//(6pi), in S.I units. (Take g=10 m//s^(2) )

Show that the pressure energy per unit volume of a liquid is P.
