Reynolds Number
The Reynolds number is undoubtedly the most famous dimensionless
parameter in fluid mechanics. It is named in honor of Osborne Reynolds (1842–1912), a
British engineer who first demonstrated that this combination of variables could be used as a criterion
to distinguish between laminar and turbulent flow. In most fluid flow problems there will
be a characteristic length, and a velocity, V, as well as the fluid properties of density, and
viscosity, which are relevant variables in the problem. Thus, with these variables the Reynolds
number
arises naturally from the dimensional analysis. The Reynolds number is a measure of the ratio of
the inertia force on an element of fluid to the viscous force on an element. When these two types
of forces are important in a given problem, the Reynolds number will play an important role. However,
if the Reynolds number is very small xthis is an indication that the viscous forces
are dominant in the problem, and it may be possible to neglect the inertial effects; that is, the density
of the fluid will not be an important variable. Flows at very small Reynolds numbers are commonly
referred to as “creeping flows”. Conversely, for large Reynolds
number flows, viscous effects are small relative to inertial effects and for these cases it may be
possible to neglect the effect of viscosity and consider the problem as one involving a “nonviscous”
fluid. This type of problem is considered in detail in Sections 6.4 through 6.7. An example
of the importance of the Reynolds number in determining the flow physics is shown in the figure
in the margin for flow past a circular cylinder at two different Re values

Why some people quit their job???
Some reasons why employees quit their job (Credit to : Susan M. Heathfield ,The balance ) 1. Relationship With the Boss 2. Bored and Unchallenged by the Work Itself 3. Relationships With Coworkers 4. Opportunities to Use Their Skills and Abilities 5. Contribution of Their Work to the Organization’s Business Goals 6. Autonomy and Independence on the Job 7. Meaningfulness of the Employee's Job 8. Knowledge About Your Organization’s Financial Stability 9. Overall Corporate Culture 10. Management’s Recognition of Employee Job Performance 11.Work-life imbalance 12.Lack of decision-making 13. No career progression and growth opportunities not available . Do you think of any other reasons for employees to quit their job . please share your thoughtsThermodynamcis

Hi Robo Tec
A one of the best society of Hitec University Taxila, Pakistan.
22nd December marked the end of journey which started in the second Week of February, after the conclusion of Robo Fiesta 17. The idea which looked liked a distant dream came true through constant pursual of not a single person but with the efforts of a team that started with few, ended with many! I would like to thank all those who helped us in achieving our goal that includes HOD Mechanical, my colleagues, Admin, DSA, students and above All Hi Robo Tec team.I was overwhelmed with the effort that was put in by the team who slept on floor to make it a successful event!
Albeit there is always a room of improvement and lessons to be learned but this is just the start and its always difficult to take the first step!!
Although the two days were so hectic that it is even hard for me to believe that yes i have a house and a room where i have a bed and where i can sleep but the entire tiredness is wept away by a message from a 4th Grade student who after seeing the event is so excited that the first thing on next morning he wants, is to build his own Robot 
🙂 .
I hope its just the start and one day in sha Allah we will reach a level where we will be trend setters instead of trend followers!!
Together we can do it in sha Allah!!
