Heat Transfer vs Leadership
I got this from a great boy in media 1213 and i could not wait to post this because of the amazing story.
5th April 2013, I studied Transport Phenomenon from Fundamentals of
heat and mass transfer book (sixth edition). I studied it to prepare my
mid-term test. When I read the first chapter, it was about Introduction.
“So, what is heat transfer?”, “Heat transfer is thermal energy in
transit due to a spatial temperature difference”, that was the book
said, i didn’t change the words at all. Hence, I conclude from that
definition, if there is a temperature different, heat transfer must
Heat transfer it self have many types, types of heat
transfer processes called by modes namely conduction, convection, and
radiation. When a temperature gradient exist in a stationary medium,
which may be solid or fluid, we use the term conduction refer to the
heat transfer that will occur across the medium. In contrast, the term
convection refers to heat transfer that will occur between a surface and
a moving fluid when they are at difference temperature. The third mode
of heat transfer is termed thermal radiation, thermal radiation based by
electromagnetic wave which emitted by a surface of matter in finite
temperature. Hence, in the absence of intervening medium, there is net
heat transfer by radiation between two surface at different temperature.
Actually, mass transfer using all modes, but when we categorized a
system, only one mode which dominates the other modes. We can
summary that conduction using static medium, convection using moving
medium, and radiation does not need medium to transfer thermal energy.
After we read the explanation above, we can know that there are several
important point of heat transfer, that are temperature, thermal energy,
medium, and electromagnetic wave. There is strong relation between heat
transfer and leadership, temperature is like confident, thermal energy
is like influence, medium is like message, electromagnetic wave is like
charisma. From this definition, we can categorized people into 3 types
of leadership. 1. Radiation Leadership Radiation leadership
is highest level of leadership. In daily life, we call it with aura,
leadership aura. If people who have radiation leadership near from us,
immediately we respect him. We are not aware why we respect him. This
feeling is like a magic. When we near from them, we try to do the best,
whereas they didn’t ask us, we feel comfort beside them and want
together with them every time. Have you ever met people like this?
People with this leadership type didn’t use message to influence the
others people, but they using their charisma, something invisible but we
can feel it, like electromagnetic wave.
The question is, how
to be people with radiation leadership? Just patient, i will tell you
when i read radiation chapter from Fundamentals of heat and mass
transfer book, in chapter 12 pages 723 (now I read introduction pages 3
2. Conduction Leadership Conduction leadership is
higher than convection leadership. Contra with radiation leadership,
conduction leadership use message to influence the other people. But the
message is in general form, no command in that message, especially
command for our self. Although the message is in general form, but we
feel moved to do the message.
3. Convection Leadership The
last type of leadership is convection leadership. Convection leadership
use command to make the other accomplish our message. This type of
leadership is the lowest level of leadership, because we must command
the other to do their obligation.
Different temperature is
absolute to move the thermal energy. Different temperature or different
level of confident distinguish which is the leader and which is the
follower. That is about my story today when I learning transport phenomenon , how about your story when you study your subject?
