# Quick Answer: What Is Fluid Mechanics And Machinery?

## What is control surface in fluid mechanics?

In fluid mechanics and thermodynamics, the control volume is a volume fixed in space or moving with constant velocity (no acceleration) through which the fluid (it could be gas or liquid) flows.

The surface enclosing the control volume is referred to as the control surface..

## Who is the father of fluid mechanics?

Leonardo da VinciLeonardo da Vinci: Father of fluid mechanics.

## Why is fluid mechanics so hard?

Fluid mechanics is by far the most difficult subject in undergrad engineering. The derivations and assumptions can be really difficult too. … Fluids is something that a lot of people get through with memorization, however I would recommend spending the time to understand the basic fundamental concepts.

## What are the 3 properties of fluids?

There are three physical properties of fluids that are particularly important: density, viscosity, and surface tension. Each of these will be defined and viewed briefly in terms of molecular concepts, and their dimensions will be examined in terms of mass, length, and time (M, L, and T).

## What are the 4 properties of fluids?

Some of the most fundamental concepts of fluid properties are temperature, density, and composition. Mass and volume are examples of extensive properties, which are properties that depend on the amount of material. Density, temperature, and pressure are examples of intensive properties.

## What is the difference between system and control volume?

A control volume is quite a specific concept – a region of space inside some closed surface. Control volume is almost always of finite dimensions and with well defined boundary. A system is a more general concept – a set of objects, usually sharing some property.

## What is control volume in fluid mechanics?

Control volume is a volume in space of special interest for particular analysis. The surface of the control volume is referred as a control surface and is a closed surface. The surface is defined with relative to a coordinate system that may be fixed, moving or rotating.

## What is fluid mechanics used for?

Fluid mechanics is the study of fluid behavior (liquids, gases, blood, and plasmas) at rest and in motion. Fluid mechanics has a wide range of applications in mechanical and chemical engineering, in biological systems, and in astrophysics.

## What are the commonly used tools and equipment for fluid mechanics?

Equipment:Low speed wind tunnel.Smoke tunnel.Open-channel flow apparatus.Jet arrangement.Viscometer.Reynolds apparatus.Digital manometer.U-tube manometer.More items…•

## What are the two branches of fluid mechanics?

Fluid dynamics is one of two branches of fluid mechanics, which is the study of fluids and how forces affect them. (The other branch is fluid statics, which deals with fluids at rest.)

## What is the concept of fluid?

In physics, a fluid is a substance that continually deforms (flows) under an applied shear stress, or external force. Fluids are a phase of matter and include liquids, gases and plasmas. … Also substances with a very high viscosity such as pitch appear to behave like a solid (see pitch drop experiment).

## What are the principles of fluid mechanics?

The basic fluid mechanics principles are the continuity equation (i.e. conservation of mass), the momentum principle (or conservation of momentum) and the energy equation. A related principle is the Bernoulli equation which derives from the motion equation (e.g. Section 2.2.

## What are 2 characteristics of all fluids?

In conclusion, two fluid characteristics are “Viscosity” and the “Absence of shape memory”.

## What is fluid mechanics system?

The word system refers to a fixed mass with a boundary. However, with time the boundary of the system may change, but the mass remains the same. … But the mass does not move out of the boundary since by definition system is a fixed mass. The definition does not prevent work or energy crossing the boundary.

## What are five properties of fluids?

Ans: Thermodynamic properties of fluids are density, temperature, internal energy, pressure, specific volume and specific weight.
