If temperature increases then viscosity
Did you know?
WebThe viscosity of liquid is inversely proporional to the square of the temperature, therefore as we increase the temperature, the viscosity of liquids will decrease. Similarly, the … Web2 feb. 2011 · The temperature dependence of the viscosity of Newtonian liquids is such that the viscosity decreases with temperature, and in general, the higher the viscosity, …
WebIncrease in temperature causes a decrease in viscosity of liquid. Now, in liquid molecules are closely packed. So, we neglect molecular momentum transfer. Another criteria we consider is cohesion force. Now, as temperature increases cohesion force decrease. So, fluid can easily flow that means viscosity decrease. For gases : WebAs the temperature increases, the molecules carry more momentum and collide more often, that means more viscosity for gas. As the temperature increases, the time of interaction between neighboring molecules of a liquid decreases because of the increased velocities of individual molecules.
WebHowever, at high pressure, the viscosity of gas decreases as the temperature increases. At intermediate pressure, the viscosity of gas may decrease as the temperature increases, but then it increases with further increase in temperature. Variation of gas viscosity with pressure is shown in Figure 5.12, and it varies between 0.01 and 0.04 cP. WebAs temperature increases, coefficient of viscosity decreases.
