Now, if we look at the speed at which both are emptying through the hole, I think it is clear to everyone that the glass of honey will take longer to empty than the glass of water. We both fill them, one with water and the other with honey. To understand the above, let’s imagine two equal glasses, each with an equal hole in the bottom. that influence, but it is clear that the viscosity has an important influence. Of course, there are also terms such as the dimension of the hole, the shape, the depth to which it is located, etc. The fluid opposes the movement and therefore, this opposition, which is due to viscosity, is what regulates the speed with which the liquid comes out of the hole. When we are going to let a liquid come out of a container, through a hole, its speed depends in part on the viscosity. Something very important to understand the term is to understand that viscosity occurs because the different molecules of the fluid interact with each other. Only solids can withstand shear stresses without moving in the case of liquids, necessarily when they are subjected to this type of effort, movement occurs. What is viscosity? Well, the viscosity is the property that tells us how much is the resistance of a fluid to be cut when it is in motion. The lower the interaction between the molecules of a liquid, the lower its viscosity, therefore there is less friction.
Liquids have a cohesion between their molecules that is weaker than a solid and stronger than a gas, which gives them the fluidity that characterizes them. To understand both concepts, it is necessary to take into account that the viscosity of a fluid is determined by the level of cohesion of the molecules. In this way, it is important to know how liquids move in order to understand how mechanisms actuated by liquid fluids work.
In hydraulics or fluid mechanics, dynamic viscosity and kinematic viscosity are necessary concepts to relate the forces that generate motion and velocity in a liquid. Question bank for Civil Engineering (CE).The basic difference between kinematic and dynamic viscosity is that dynamic viscosity and kinematics are values that determine the movement that a certain liquid or fluid has under specific conditions.
