Apart from the numerous atrocities we've had to undergo in Mech through many preposterous acts by the aged people of IITM, there are a few gems too. Sample this: Skd, who said this in one of the classes:
'I have no reason to believe in God. But when I realize that one of the most efficient heat exchangers ever made in the past or the present is our throat, I have a strong reason to believe in God'.
Yes, it is indeed true. If you were living in a cold place with a room temperature of -10 deg, the air at that temperature could kill you. In microseconds, before the air reaches your lungs, the upper respiratory system acts as a regenerative heat exchanger (similar to fluidized bed) and brings the temperature to the body temperature. Brilliance.

Ah!
gasp!
that's my fact for the day! cool, never knew this..
Wow ! And they think God is a civil engineer, infidels :-)
Btw, how is it like a Fluidized Bed ?
The air which goes out of our body is hotter than the body temp, hence heats up the upper respiratory system . It is this heat that the throat uses to heat up the cold air coming in! In other words, it stores heat for sometime, hence a storage heat exchanger.
regenerative may be appropriate to use but not fluidized bed. many of my batchmates who attended SKD class say that he is more at self dabba during class than the subject. let me see ur views on SKD as you end the course.
