Transportation Is Omnipresent!

By -
Good evening,

Wishing you all a great weekend ahead. As we plan to move from one place to another,even physical quantities such as energy, mass, momentum have the same tendency to move from one place to another. These 3 basic fundamental quantities Energy, Mass and Momentum make there journey in  a road map with their own choices/modes. The Common driver for all these 3 passengers(Energy, Mass & Momentum)/ anyone  is  Time. Without him, We will not be able to know their location. There is always a purpose behind any transportation,and these purposes are their coefficient, namely  Conductivity, Diffusivity, & Viscosity. Ultimately,A task with some purpose is guided for some application. That is why we need conductivity, diffusivity & viscosity.



3 Travelers of the day, Energy Mass & Momentum



Thermal Conductivity is a proportionality constant in  Energy Transport phenomena, where The Flux/ Flow(Heat Flux) is directly proportional to Temperature Gradient .

The above picture explains the concept of Thermal Conductivity

Diffusivity is a proportionality constant in  Mass Transport phenomena, where The Flux/ Flow(Diffusion Flux) is directly proportional to Concentration Gradient.

The above picture explains the concept of Diffusivity

Viscosity is a proportionality constant in  Momentum Transport phenomena, where The Flux/ Flow( Viscous Drag) is directly proportional to Velocity Gradient .





The above picture is a comparative study between the viscous flow of Water & Oil,



From the above 3 statements we can say that the transportation/flow is always proportional to Gradient of the Transportation Mode.



To put this concept across, Let me narrate a Real Life example. Imagine that you are a traveler who would like to reach some place which is ~2000 Kilo meters away from your town. Say for example, You are travelling from Bangalore to Delhi. If you are in hurry, then best mode of transport is by air and the aerial distance is  1750 Kilo meters. The referee of your journey is very well experienced driver "Time" he says that your travel is ~3 Hours. If the same journey is made through the train,where the distance is 2375 Kilo meters. The referee says your travel is ~3 Days. 
Suppose, Imagine if you are travelling on your own, The referee waits till you reach, your wish, your distance, your time. 

These things are the application part of the transport phenomena. In this application world, If you are using Graphene, its thermal conductivity is high there by the material is recommended for very good- quick heating gadget which can make our life easy.
Imagine if your using the mode to be wood/glass, there it can be used as road blocks. Where we need to resist the heat flow.
Glass/Graphene, both are used for different applications.

Application world, Graphene V/s Glass..


Bottom Line: Transportation is a need indeed for human beings as Materials do Transport.
Transportation of Words with Vocabulary, Signs  leads to  Communication.  This phenomenon is also applicable even to satisfy our hunger, the digestion factor remains as the constant for this transportation. Finally, I think Transport phenomena is Omnipresent.

Network modifiers in glass system: A Tribute to all who made me what I am today

Dear Friends, This article is based on my understanding  on the modifiers and the way how our formed network changes. As these modifiers possess higher coordination number and lower valency as discussed in article 50, where we know the rules for glass formers in oxide glasses, I wish to correlate this concept with the methods for survival in this inferior society. The role of glass formers are really idealistic one. We can never be so pure/ in other words, the world doesn’t accept ideals, they need someone who can dance to their tunes. The one who makes you dance and the way how we look at the transparency dance to attain its stability is because of these modifiers. Glass as we know it is an amorphous solid with 3D network. This network has to be broken, that can be done by modification, that responsibility is taken care by network modifiers. I wish to list few interesting correlation on these modifiers on how they break our virtuousness.  The above periodic table indicates

Transitive Law - Zeroth Law of Thermodynamics - Holding Life Together

Good noon friends, The relationship between Mathematics - Physics - Chemistry (Pure Sciences) is come in hand together as all of them are interdependent. According to Mathematics, The transitive relation in equality, If A= B, and B= C, then C= A. This looks simple, but where is an example to it?? The example for most of the mathematical expressions are given by Physics, The Zeroth Law follows the above relation, Where it states that "When 2 systems are in contact with each other to another system, then all the three systems are in contact with one another" Which depicts the thermal equilibrium. On similar lines,we are always interdependent to ourselves,This Law reminds me 3 System that are in contact for human Life, Physical+Emotional+Mental. I have believe that if any of those 3 systems are corrupted, then the whole system is hanged, sometimes it may lead to a catastrophe. The above image clearly speaks on Zeroth Law of Thermodynamics. To know imagine this

EXERGY IS WHAT WE MUST GAUGE!

Dear Friends, I have always heard that matching someone’s energy is tough/someone’s capability would be often referred to energy. I have heard few of my friends stating that, “It is tough to match energy of some great person”. It is not energy that we must look at. Now, I realized that exergy is the parameter which defines the ability of a person, it is not energy.  The total energy of the system is a combination of Exergy as well as Anergy. Exergy of a system is referred as the available energy to do useful work whereas the anergy deals with energy which does not produce useful work.  Most of us, use energy as a parameter to gauge the capability of a person/system. But due to conservation laws, we don’t get exact/ideal cases of a system. The moment we deal with exergy, it doesn’t obey conservation laws as it clear to states. For example,  out of 100 Joules; I can burn only 20 Joules, remaining 80 Joules is within the system. That unaccounted 80 Joules of energy is the
