In steady flow pathline and streamlines are mcq?

This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!

A streamline is an imaginary line within the flow that is constructed in such a way that the tangent at any place on it indicates the velocity at that location. In contrast, a pathline is the path that is taken by a particle while it is in motion. Explanation: When there is a steady flow, the velocity at any given point stays the same over the course of time.

What are the similarities and differences between the Pathline and the streamline in a steady flow?

Streamlines are a class of curves that are instantly tangent to the velocity vector of the flow. Streamlines are used to represent the flow of water and other fluids. They indicate the course that a massless fluid component will take at any given point in time… Each fluid particles each travel along their own unique pathlines, also known as trajectories.

Is it possible for there to be a constant and uniform flow inside another?

Is it possible for there to be a constant and consistent flow within a nozzle? If the water level is not kept at a constant level by supplying water at the same rate as it is discharged, then there will be an unsteady flow because the water level will gradually decrease over time. However, if the water level is maintained at a constant level by supplying water at the same rate as it is discharged, then there will be a steady flow.

What will the contour of the pathline for a flow in one dimension look like, Mcq?

What will the contour of the flow path look like if it is only one dimension? The solution is… when there is only one dimension of movement, the fluids only move in that one dimension. Because of this, the pathline will be a straight line as well.

What is meant by the terms steady flow or streamline flow?

The streamlines are maintained in a constant flow, and the fluid moves along a route that is smooth and consistent. This ensures that the flow characteristics at each place, such as velocity, pressure, and so on, stay unchanged. While attempting to understand streamline flow, one must first consider laminar flow, which consists of laminae, which are essentially very thin layers that are all parallel to one another.

Streamline, Pathline, and the Example of Steady Flow

Explain in an example the concept of flow in streamline.

It is possible to characterize a flow as a streamline flow or a laminar flow if there are no turbulent oscillations in the velocity of the flow… These streamlines are created in such a way that the tangent to the streamline at any one place in space is aligned with the instantaneous velocity vector at that position at any given instant in time.

Explain the meaning of flow in the context of streamlining with an example.

What exactly is meant by “Streamline Flow”? Streamline flow in fluids is defined as the flow in which the fluids flow in parallel layers such that there is no disruption or intermixing of the layers and at a given point, the velocity of each fluid particle passing by remains constant with time. Streamline flow is characterized by the absence of any intermixing of the layers and the presence of no disruption of the layers.

What is the mathematical formula for the Pathline?

These equations determine the pathline for any given time interval and can be used in any situation. In order to obtain an explicit equation for the pathline, we can remove the parameter t from the previous two equations and arrive at the following: (x X)2 = 2a2 9b y3 (for the sake of convenience, we have set b/a2 = 16/9)

Which one is accurate, Mcq?

A multiple-choice question, also known as an MCQ, is made up of two components: a stem, which identifies the question or problem, and a set of alternatives or possible answers, which includes a key, which is the answer that is considered to be the most appropriate response to the question, as well as a number of distractors, which are answers that are plausible but not the correct response to the question.

What exactly is a flow that just has one dimension?

a flow in only one dimension It is the flow in which all of the flow parameters may be represented as functions of time and just one space coordinate at a time. In most cases, the distance that is measured along the center-line (which does not necessarily have to be straight) in which the fluid is flowing is the single space coordinate.

How are we going to find out if the flow is laminar or turbulent Mcq?

Explanation: It is possible to tell from the value of Reynold’s number whether the flow is laminar or turbulent. If the value of Reynold’s number is less than 2000, the flow is said to be laminar. If the Reynold’s number is larger than 2000, then the flow in question can be classified as turbulent.

What exactly does it mean to have flow in two dimensions, Mcq?

A. the velocity in every direction and at every point is the same in both its magnitude and its direction. At any given position, the velocity of several fluid particles moving in the same direction will remain constant throughout subsequent intervals of time. There is no shift in the amount or direction of the velocity as one moves from one place in the fluid to another.

What kind of flow can be assumed to occur in any pipe with constant cross-sectional area?

No matter how fast or slow the rate of flow is, a pipe with a constant cross-section will always have the same flow velocity inside of it, regardless of how fast or slow the rate of flow is. As a result, there won’t ever be any variations in the flow.

What exactly is the steady flow?

A steady flow is one in which all conditions at any given location in a stream stay consistent with respect to the passage of time… The precise term for this phenomenon is the mean constant flow. A steady flow can either be uniform or non-uniform in its distribution. Continuity throughout. A flow is said to be genuinely uniform when, at any given instant, the velocity of the flow is the same at every location in the fluid.

What is the difference between steady and erratic flow?

The term “steady flow” refers to any flow that is not dependent on the passage of time. The condition known as steady-state flow describes a situation in which the physical characteristics of the fluid at a given place in the system do not vary as time passes. Unsteady flow, commonly referred to as transient flow, is flow that is depending on time… This more or less indicates that all statistical qualities remain unchanged during the course of time.

When the railroad went through the Will the streak line and the path line be identical?

All three lines, namely the streamline, the route line, and the streak line, must be identical for there to be a steady flow. A streamline is an imaginary line that is drawn across a fluid that is moving in such a way that the tangent to it at any point indicates the direction of the flow velocity at that location. A streamline can be constructed at any point along the path of the fluid.

What exactly is an example of a MCQ test?

Multiple choice questions are fundamental survey questions which provides respondents with several answer possibilities. … These are the most fundamental questions that can be asked in a survey or questionnaire, and the respondents are expected to choose one or more than one choice from the several possible answers.

How do I prepare for MCQ?

The multiple choice questions of the examination
  1. Rephrase the question while ensuring that the essential meaning of the query is maintained.
  2. Think about whether each of the options represents a true or incorrect statement.
  3. Reasoning can help you eliminate incorrect solutions, increasing the likelihood that you will choose the correct option.
  4. Keep an eye out for qualifiers that can throw you off.

What exactly is a MCQ test?

Multiple choice, also known as objective response or MCQ (which stands for multiple choice question), is a type of objective assessment in which respondents are asked to select only the appropriate responses from a list of options that are shown to them…. In 1982, Sole developed the very first multiple-choice test for computers, which he did on a Sharp Mz 80.

How do you compute streamlines?
