the resistance of liquid to following is its viscosity.
What is the difference between the Plastic Viscosity and Apparent Viscosity of a drilling fluid?
Both are same
What is viscosity in mechanical engineering?
Viscosity is the resistance offered against shear force by a fluid.
A fluid resistance to flow is called?
A fluid's resistance to flow is called its viscosity.
What refers to the tendency of oil to resist flowing?
Oil viscosity depends on it's temperature. The higher the oil temperature is, leads to higher viscosity and low flow resistance. Cold oil temperature leads to lower viscosity and higher flow resistance
Does temperature directly proportional or inversely proportional to the kinetic and dynamic viscosity?
Temperature is inversely proportional to the dynamic viscosity, which is the measure of a fluid's resistance to flow. As temperature increases, the dynamic viscosity of a fluid typically decreases. However, for some fluids, the kinetic viscosity, which is dynamic viscosity divided by the fluid density, can increase with temperature due to changes in the fluid's density.
What is the mechanism for this change in viscosity with heat?
As temperature increases, the kinetic energy of the molecules also increases, causing them to move more freely. This results in reduced friction between the molecules and a decrease in viscosity. Conversely, at lower temperatures, the molecules have lower kinetic energy and move less freely, leading to higher viscosity.
What happens to viscosity of a gas when it is cooled?
When a gas is cooled, its viscosity typically increases. This is because cooling reduces the kinetic energy of the gas molecules, leading to a decrease in their speed and a higher likelihood of intermolecular interactions, which results in higher viscosity.
Temperature and viscosity are inversly related higher temperature means lower viscosity?
Yes, that's correct. As temperature increases, the viscosity of a substance decreases. This is because higher temperatures increase the kinetic energy of molecules, causing them to move more freely and reducing their ability to stick together, leading to lower viscosity.
What is kinetic theory and how is it used?
Kinetic theory is when a high number of particles such as temperature, viscosity and volume that move randomly colliding in different directions. The speed of particles has an impact on temperature and gas pressure.
State any one factor which determines the kinetic energy of a body?
One factor affecting the kinetic energy of a particle (or body) in is the viscosity of the medium through which that particle moves
Why viscosity increases to decrease temperature?
Viscosity tends to increase as temperature drops in most liquids because the kinetic energy of the molecules reduces. This allows the intermolecular forces to get molecules attracted giving the fluid more resistance to flow. Interesting though, in gases at low pressure viscosity increases with T1/2, where T is the thermodynamic temperature.
What happens to viscosity as temperature increases?
As the temperature rises, the viscosity, meaning a substance's resistance to flow decreases because a liquid based substance melts, and flows more.Viscosity decreases as temperature increases.
Why the viscosity of liquid decrease whaile that of agas increase with an increase in temperature?
As temperature increases, the kinetic energy of molecules in a liquid increases, causing them to move more freely which decreases the viscosity of the liquid. In gases, an increase in temperature also increases the kinetic energy of the gas molecules, leading them to collide more frequently and with higher energy, which increases the overall viscosity of the gas.
How is viscosity affected by the cold?
In general, viscosity tends to increase as temperature decreases, meaning liquids become more viscous in colder temperatures. This is because colder temperatures slow down molecular movement, causing molecules to have less kinetic energy and move more sluggishly, resulting in higher resistance to flow.
Why tempertrue affects viscosity?
Temperature affects viscosity because it influences the movement of molecules in a substance. When temperature increases, molecules gain more kinetic energy and move faster, causing them to flow more easily and reducing viscosity. Conversely, lower temperatures lead to slower molecular movement and an increase in viscosity.
What is the difference between viscosity and viscosity index?
Viscosity is resistance to flow of oil Viscosity Index is a scale to measure viscosity
