Define coefficient of viscosity

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

The relationship between the coefficient of viscosity of a liquid and temperature can be expressed as

In an experiment to determine the coefficient of viscosity of a liquid using the formual eta=(piPr^(4))/(8l Q) the radius of the capillary tube was measured to be 0.41 mm using an instrument of least count 0.001 cm, length l was measured usinga metre scale as 15 cm. The percentae error in the pressure difference is 0.4% and the percentage error in the volume of the liquid flow out per second Q is 0.3% what is the maximum percentage error in the coefficient of viscosity?

Which one of the following represents the correct dimensions of the coefficient of viscosity?

If mass M, area A and velocity V are chosen as fundamental units, then the dimension of coefficient of viscosity will be:

A small metal sphere of radius a is falling with a velocity upsilon through a vertical column of a viscous liquid. If the coefficient of viscosity of the liquid is eta , then the sphere encounters an opposing force of

The flow rate from a tap of diameter 1.25 cm is 3 L//min. The coefficient of viscosity of water is 10^(-3) pa-s. Characterize the flow.

The critical velocity v of a body depends on the coefficient of viscosity eta the density d and radius of the drop r. If K is a dimensionless constant then v is equal to
