![]() The kinematic viscosity of water is 1.00410-6. The change in velocity from layer to layer gives rise to shear stress in the fluid. At 20 degrees Celsius, the dynamic, or absolute, viscosity of water is 1.00210-3, or 0.001002, Pa.s.The fluid layers in between the plates slide parallel to one another on account of molecules having different momentum crossing the fluid layers.The fluid layer in contact with the upper plate will move with velocity u and the fluid layer in contact with the lower plate, which is at rest will not move and will have zero velocity.Water at 20 C has a kinematic viscosity of about 1 cSt. ![]()
