What are the characteristics of laminar flow?
Laminar flow is defined as the movement of liquids without turbulences.
The fluid flows in parallel layers with no disruption between them..
Which among the following does not depend on the friction factor?
Which among the following does not depend on the friction factor? Explanation: The friction factor(f) depends on the velocity of flow, fluid density, pipe diameter and the viscosity of the pipe. Roughness of the pipe is also an important criteria to determine the friction factor.
What is meant by correction factor?
correction factor (plural correction factors) A factor that is multiplied with the result of an equation to correct for a known amount of systematic error.
What is the function of Reynolds number?
The purpose of the Reynolds number is to get some sense of the relationship in fluid flow between inertial forces (that is those that keep going by Newton’s first law – an object in motion remains in motion) and viscous forces, that is those that cause the fluid to come to a stop because of the viscosity of the fluid.
What is the momentum flux correction factor?
The momentum-flux correction factor ( ) is defined in such a way that the integral form of the momentum flux into or out of the control surface at an inlet or outlet of cross-sectional area can be expressed in terms of mass flow rate through the inlet or outlet and average velocity through the inlet or outlet.
What is entry loss?
[′en·trəns ‚lȯs] (fluid mechanics) Energy loss by friction in a flowing fluid when it moves into a cross-sectional area of sudden contraction, as at the entrance of a pipe or a suddenly reduced area of a duct.
Why do we need a model analysis?
Why do we need a model analysis? Explanation: One of the major advantages of the model analysis is that we can predict the alternative designs. It provides the safest design in the most economical way. Explanation: Kinematic similarity is defined as the similarity between motion of the model and the prototype.
What is the difference between correction and correction factor?
The relative detector response factor, commonly referred to as response factor, expresses the sensitivity of a detector relative to a standard substance. The correction factor is the reciprocal of the response factor.”
What is energy correction factor and 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 total loss developed in a series of pipes *?
2. What is the total loss developed in a series of pipes? Explanation: When the pipes of different diameters are connected in series from end to end to form a pipe line. The total loss so developed is equal to the sum of local losses plus the losses in each pipe.
What is a good Reynolds number?
If the Reynolds number is less than 2300, the flow is laminar. Any Reynolds number over 4000 indicates turbulent flow. In between these values indicates transient flow, which means the fluid flow is transitioning between laminar and turbulent flow.
Which one of the following is major loss?
1. Which one of the following is a major loss? Explanation: The major loss for the flflow through the pipes is due to the frictional resistance between adjacent fluid layers sliding over each other. All other losses are considered to be minor losses.
How do you find the correction factor in chemistry?
In order to determine the correction factor, subtract the final reading from the true volume.
What is a correction value?
Correction values are transaction data. The definition of correction values is versioned. For better auditability, changes are recorded with the user name or the process and time stamp. Correction values can be positive or negative. The system interprets a non-existent correction value as a zero value.
Is laminar a flow?
Laminar flow or streamline flow in pipes (or tubes) occurs when a fluid flows in parallel layers, with no disruption between the layers. At low velocities, the fluid tends to flow without lateral mixing, and adjacent layers slide past one another like playing cards.
What is critical Reynolds number?
1 Critical Reynolds Number. A critical Reynolds number is determined as a limit where the laminar flow changes to turbulent flow. If the calculated NRe is greater than the critical Reynolds number NRec, the flow regime is turbulent; otherwise the flow regime is laminar.
What is the value of kinetic energy correction factor during a laminar flow?
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.
