Ever seen lubricant-kah? motor oil ... that guy would know, because every day kebut2an on the road. He2 .... Try to compare oil with water. Which is more viscous? Ah, this gurumuda. Just so why Nanya ... oil more viscous dunk. Ich, clever girl ... now turn. If a girl khan close with my mom, so it must know cooking oil. Well, if the child mami, surely can only savory stew noodles ... piss .... Which is more fluid, cooking oil is more viscous or iced tea? iced tea sd-lah ... children can also be responsible. Ich, pinter2 nacho cheese warmer yes, students today ... Hehe ... btw, on this occasion we will study the viscosity nacho cheese warmer of a fluid, either gas or liquid substance. Fancy term viscosity. nacho cheese warmer Viscosity = fluid viscosity measure. Met learn ya ... hopefully arrive safely at their destination
Fluid, either liquid or gas substances of different types have different viscosity. Ever see the water right? what used gurumuda water wells, tap water, drinking water, fresh water, white water mah ... he2 ... this same type, just different name ... mean gurumuda vocation is a different kind of liquid ... such as syrup and water. Syrup is usually more viscous than water. Water or milk, cooking oil, oil, blood, nacho cheese warmer et al .... Add the own level of the liquid viscosity any different. Btw, in general, more viscous liquids tuh of gas substances.
Viscosity viscosity alias is actually a friction force between the molecules that make up a fluid (the fluid that can flow tuh substance, in this case the liquid and gas substances forget ya ... do not use). The term jock, the viscosity of the fluid tuh internal friction (internal = in). So the molecules that form a fluid-friction rub each other when the fluid flow. In the liquid, the viscosity due to the cohesive forces (attractive nacho cheese warmer forces between molecules of a kind). While the gas substances, viscosity nacho cheese warmer caused by collisions between molecules.
Usually more liquid fluid flows more easily, for example water. Conversely, the more viscous fluid flows more difficult, nacho cheese warmer eg cooking oil, oil, honey et al. You can prove with water and pour cooking oil over the surface sloping floor. Ngalir water definitely faster nacho cheese warmer than cooking oil or oil. Viscosity of a fluid is also dependent on temperature. The higher the temperature of the liquid, the less viscous the fluid. For example, when the mother's thigh frying fish in the kitchen, cooking oil initially becomes more viscous liquid when heated. Conversely, the higher the gas temperature of a substance, the more viscous the gas substances.
Anyway, please note that the alias viscosity fluid viscosity only exist in real (rill = real). Real fluid / fluid tuh apparent that we encounter in everyday life, such as water, syrup, oil, exhaust fumes, et al .... Different from the real fluid ideal fluid. Ideal fluid does not actually exist in everyday life. Ideal fluid model is only used to assist us in analyzing the flow of fluid (the fluid that we use this ideal in subject Fluid Dynamic). Much like we think of objects as a rigid body, whereas in everyday life is actually no objects are really strong / stiff. The goal is the same, let us be more simple analysis does not beribet alias. Ok, back to the laptop ....
Viscosity of the fluid is denoted by the symbol (read: eta). This letter of the Greeks. Aneh2 the greek letters, next to the long legs, short next ... = coefficient of viscosity. So the viscosity of a fluid is expressed by the coefficient of viscosity of the fluid. Mathematically, coefficient of viscosity can be expressed by equations. Now, prepare enough ammunition ... we will derive the equation of the coefficient of viscosity. To help reduce the equation, we review the motion of a thin layer of fluid is placed between two parallel plates. Ok, step on the gas ... Stare at the picture below with tenderness
Thin fluid layer is placed between two plates. Gurumuda deliberately gave a blue color on a layer of fluid that is in the middle, let you easily understand the explanation gurumuda. Still remember the cohesion and adhesion are not? cohesion tuh attractive forces between molecules similar, whereas the adhesion tuh attractive forces between the molecules are not similar. Adhesion force acting between the plate and the fluid layer that sticks to the plate (the fluid molecules and the molecules attract each plate). While working nacho cheese warmer in the cohesive forces between the membrane fluid (the fluid molecules attract each other).
At first plate and the stationary fluid layer (figure nacho cheese warmer 1). After the plate that is on the top is pulled to the right (Figure 2). Existing plate on the bottom is not withdrawn nacho cheese warmer (the lower stationary plate). Large tensile nacho cheese warmer force is set such that the existing plate on the top right of the shift to fixed rate (fixed v). Because no adhesion force acting between nacho cheese warmer the edge of the plate with the fluid part ne
