As we saw in first post what is chemical engineering? It is diverse engineering branch and covers many fields. Fluid mechanics is one of them.
Fluid Mechanics is that part of applied mechanics, which is concerned with the statics and dynamics of liquids and gases.
Simply, it is the study of forces and flow within fluids.
A knowledge of fluid mechanics is essential for the chemical engineer because the majority of chemical processing operations are conducted either partially or totally in the fluid phase. Such knowledge is especially valuable for solving problems in the biochemical, energy, mining, chemical, polymer, fermentation, materials, vast – processing and petroleum industries.
Is fluid mechanics in chemical engineering is same as in other engineering branch ?
” Concept remains same everywhere. Either you study it in this branch or in other branch. Fluid mechanics will be fluid mechanics.” By Dr. Dharmendra D. Mandaliya
Well, fluids will behave same everywhare. They don’t know whether you are using them for chemical or other engineering reasons. The main difference is scale and application of fluid mechanics in chemical and other engineering branches. Chemical engineers generally interested in microscopi systems like turbulent flow, boundary layer, flow in pipes, mass and heat transfer in fluids etc. They are not concern to hydrostatics. Wherein, other engineering branches like civil and mechanical engineering, they are interested in macroscopic systems like hydraulic machinery, fuel flow control systems, pneumatics, drainage basins, canals, sewage treatment plants etc. So they are much concern to hydrostatics.
So why to study fluid mechanics ?
In last three centuries, we humans discovered many things in nature. But there are still many phenomena is undiscovered in nature and even in our body itself.
By learning fluid mechanics, we can study and understand natural phenomena. So that we can develop a sustainable world, green energy, new habitable place in cosmos and evolve our self for better future.
Fluid mechanics gives answers of many day to day life questions like how planes fly in air ? How thousands of tons weighted ship floats over water ?why racing cars have less height then other cars? Why foot ball goes in curve path when footballer kicks ball? Why tornado have cone shape? How engineers measure flow rate and pressure in pipe? How they forecast about weather? How blood circulate in our body? And there is countless questions which answer can given by fluid mechanics.
Fluid mechanics is itself wide section of physics it’s applied to nearly all major engineering problem and research field.
Some of the applications are
- In aerodynamics
- In wind tunnel for testing materials
- Hydraulic presses
- Pump and motor
- Refrigerator and air conditioners
- Hydraulic Jack for lifting heavy loads
- Water slides and roller coasters
- In biological & medical applications
So it is the basic subject to engineering branch.
In my next post I will tell you what will you learn in fluid mechanics in B.Tech course in chemical engineering and how to learn and become master of it.
