Question

define viscosity and write SI unit of coefficient of viscosity​

Answer 1

Answer:

The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. ... A fluid with a high viscosity, such as pitch, may appear to be a solid.

• SI unit of coefficient of viscosity is termed as ' deca-poise'.
• In terms of CGS is 'poise'.

Answer 2

SI unit of coefficient of viscosity is Newton-second per square metre ( It is equivalent to Pascal - seconds. Its dimensional formula is. Its SI unit is also termed as 'deca-poise' and CGS unit is 'poise
