The higher the viscosity, the more resistance the fluid has to flow.<\/p>\n<p>The units of viscosity are newton-sec\/metre2. This can be written as N s\/m2 or Pa s. The units of viscosity are derived from the definition of viscosity, which is the ratio of the shear stress to the rate of strain.

Consider a fluid flowing through a pipe. The fluid is in contact with the walls of the pipe, and the friction between the fluid and the walls of the pipe causes the fluid to slow down. The rate of strain is the change in velocity per unit distance, and the shear stress is the force per unit area that is required to maintain a constant velocity gradient in a fluid. The units of viscosity are newton-sec\/metre2, which can be written as N s\/m2 or Pa s.<\/p>\n<p>The other options are incorrect because they do not represent the units of viscosity. Option A, metre2\/sec, is the unit of area. Option B, kg sec\/metre, is the unit of mass. Option D, newton-sec\/metre, is the unit of momentum.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Join Our Telegram Channel Subscribe on
