so this is el kamar saying again I am
back with another thought well this is
one of the simple total and this total
will be quite I mean short that so I
will just I'm just going to make you
understand what is convection nothing
else right so what is convection
basically suppose that there is steel
rod right and this a temperature of
steel rod is suppose that 100 degree
centigrade and there is a fluid in a
bucket you're having a fluid in a bucket
and the free.you temperature is 10
degree centigrade okay if I will put
this rod in the flavor then what will
happen up to few time after maybe two or
three minutes what will happen the
temperature of this road and Feud will
be same because a temperature here will
transfer into water and most probably
there would be equilibrium in the
temperature of fluid as well as this rod
right so what is happening that's
because of the process that is one of
the heat transfer process that is known
as convection this is happening that's
because of convection now there are two
types of conversation okay so one is
forced convection and one of the another
one is free convection in case of forced
convection we used a external body for
increasing the process of convection and
for transferring for increasing the rate
of transfer of heat from one body to
liquid or maybe gas because in case of
most of the time what is convection
basically transfer of heat from solid to
gaseous or liquid that means fluid is
known as convection so this is all about
convection what is convention but there
few laws and a few dimensionless number
we need to study I will share with you
my upcoming videos about it thanks for
watching see you soon in my next video
so why
