## What are the elements of analysis model?

The analysis model is organized into four elements—scenario-based, flow-oriented, class-based, and behavioral..

## What is the major advantage of using incremental model Mcq?

Explanation: Incremental Model is generally easier to test and debug than other methods of software development because relatively smaller changes are made during each iteration and is popular particularly when we have to quickly deliver a limited functionality system.

## What is a prototype Mcq?

Prototype is a working model of existing system. The prototyping model is a systems development method in which a prototype is built, tested and then reworked as necessary until an acceptable outcome is achieved from which the complete system or product can be developed.

## What is energy per unit head of water called as?

total energyThis set of Fluid Mechanics Multiple Choice Questions & Answers (MCQs) focuses on “Specific Energy – 1”. Hence energy per unit head is called as total energy.

## What is the meaning of prototype?

noun. the original or model on which something is based or formed. someone or something that serves to illustrate the typical qualities of a class; model; exemplar: She is the prototype of a student activist.

## Which model is not suitable for accommodating any change?

Waterfall ModelWaterfall Model is not suitable for accommodating any change. SDLC stands for Software Development Life Cycle .

## Why is it called head loss?

Pressure head is due to the static pressure, the internal molecular motion of a fluid that exerts a force on its container. Resistance head (or friction head or Head Loss) is due to the frictional forces acting against a fluid’s motion by the container.

## What is Head gain?

In fluid mechanics, head is a concept used to relate the energy (or its components such as pressure, potential or kinetic) associated with an incompressible fluid flow with the height of an equivalent static column of that fluid. It is equal to the fluid’s energy per unit weight.

## Can the flow inside a nozzle be steady and uniform?

Can the flow inside a nozzle be steady and uniform? Explanation: According to the continuity equation, ρAV =constant, where ρ= density, A= cross-sectional area of flow, V = velocity of flow. For a nozzle, the area gradually decreases towards it’s exit. … Hence, it’ll always be an unsteady flow.

## What is a model analysis?

Model based analysis is a method of analysis that uses modeling to perform the analysis and capture and communicate the results. For social problems the two main forms of modeling used are causal loop diagrams and simulation modeling. Causal loop diagrams are used for preliminary conceptual attacks on the problem.

## What conditions are required for flow similarity?

Kinematic similarity: the velocity at any point in the model flow must be proportional by a constant scale factor to the velocity at the homologous point in the prototype flow. (That is, the flow streamlines must have the same shape.)

## What is the mathematical technique used to predict physical parameters?

Dimensional analysis is a mathematical technique used to predict physical parameters that influence the flow in fluid mechanics, heat transfer in thermodynamics, and so forth. The analysis involves the fundamental units of dimensions MLT: mass, length, and time.

## Which among the following is not a criteria to achieve similitude?

Which among the following is not a criteria to achieve similitude? Explanation: The criteria required to achieve similitude are geometric similarity, kinematic similarity and dynamic similarity. All these similarities play a major role in regard with the real-time applications.

## How do you calculate piezometric head?

Piezometric total head calculations in groundwater use the formula h=z+Ψ where h means total head or height of the groundwater level above the datum, usually sea level, while z represents the elevation head and Ψ represents the pressure head. The elevation head, z, is the height of the bottom of a well above the datum.

## What are the 4 types of models?

This can be simple like a diagram, physical model, or picture, or complex like a set of calculus equations, or computer program. The main types of scientific model are visual, mathematical, and computer models.
