Nitrogen and helium, at 100°C , have the highest average kinetic energy because they have the highest temperature.

## Which of the following will have greatest average speed of its molecules?

Which one of the following will have greatest average speed of its molecules ? Thus, He at 200 K will have highest average speed.

## Are there gas molecules that move faster than the average?

-There are gas molecules that move faster than the average. -The average speed of gas molecules decreases with decreasing temperature. -All the gas molecules in a sample cannot have the same kinetic energy. -The average kinetic energy of gas molecules increase with increasing temperature.

## Which is correct for molecular speed of gases?

Hence, the correct order of speeds is Vmp

## What is Maxwell distribution law of velocity?

The Maxwell-Boltzmann equation, which forms the basis of the kinetic theory of gases, defines the distribution of speeds for a gas at a certain temperature. From this distribution function, the most probable speed, the average speed, and the root-mean-square speed can be derived.

## What is a Maxwell distribution curve?

A Maxwell-Boltzmann Distribution is a probability distribution used for describing the speeds of various particles within a stationary container at a specific temperature. In short, the graph shows the number of molecules per unit speed.

## Which experiment verify the Maxwell law of distribution of velocity?

The Maxwell-Boltzman distruction distribution has been verified experimentally by a device called a velocity selector, which is essentially a series of spinning wheels with a hole through which the gas is effused.

## What is velocity distribution in open channel?

In an open channel flow, velocity distribution is non-uniform which means velocity is different at different depths. Various Factors such as channel slope, alignment, shape, roughness etc plays key role in velocity distribution.

## What are y1 and y2 in the adjoining graph?

6. What are y1 and y2 in the adjoining graph? Explanation: For a particular specific energy above the minimum specific energy there are two depths called as alternate depths.

## What is momentum correction factor?

‘Momentum correction factor’ is defined as the ratio of momentum of the flow per second based on actual velocity to the momentum of. the flow per second based on average velocity across a section.

## What is the momentum correction factor for laminar flow?

Show that the momentum correction factor and energy correction for laminar flow through a circular pipe are 4/3 and 2.0 respectively.

## What is energy correction factor?

‘Kinetic energy correction factor’ is defined as the ratio of the kinetic energy of flow per second based on actual velocity across a section to. the kinetic energy of flow per second based on average velocity across the same section.

## What is the kinetic energy correction factor is it significant?

is the Kinetic Energy Factor. Its value for a fully developed laminar pipe flow is around 2, whereas for a turbulent pipe flow it is between 1.04 to 1.11. It is usual to take it is 1 for a turbulent flow.

## What is the coefficient of kinetic energy?

The coefficient of kinetic friction is the ratio F/w or mg/Mg , or simply m/M. Based on the data you enter, if the ratio m/M is exactly equal to the selected μ, no motion will occur. To cause motion, you need to slightly increase m, the hanging mass, by 0.1 gram, for example.

## What is the advantage of laminar flow?

Can be used to measure low flow rates. Ability to measure the flow of high viscous liquid. Linear relationship between flow rate and pressure drop.

## What is the purpose of laminar flow?

Generally, laminar air flow is designed to prevent the contamination of semiconductor wafers, some sensitive materials, and even biological samples.

## What is the difference between steady flow and laminar flow?

Steady flow means the flow does not change over time. Laminar flow means the flow is smooth with layers (or lamina) of fluid sliding smoothly past each other. This does not have to be steady flow. It is possible to have unsteady laminar flow.
