studying dis sem had been a much better experience than previous... yea haz! can onie say its interesting when i studied wif dex, xinyi, n rus... it was totally AWESOME man!!! study together, joke together, bitch together, curse some particular person together... (see? we're essentially EVIL pplz!!! so dun cross us, or we add u in de list of de gonna-kena-cursed haz!)

gotta say, we might be de lamest ppl anyone can find in NUS already haz (wif de exception of zenov tt is... u dunno wad i mean, look below...) and frm our many often-distracted attempts of mugging, we coined many new terms to accompany us to understand our stuff well haz...

Disclaimer: below is extremely Chemical Engineering so if u dun really understand wad i say, dun fret haz...

CSTR (aka Continuous Stirred Tank Reactor)

a HARDCORE chemical engineering term about some reactor in de form of a tank, stirred up so that its composition is homogeneous, and follows tt of its outlet... well if u dunno wad i mean, TOO BAD!!!

we made a literal concept of the CSTR to be used in everyday conversation, bearing in mind its original definition, with reactor composition homogeneous and equal to outlet composition...

dun understand??? lets just say tt for a CSTR, reactor composition is HOMOGENEOUS and EQUAL to the outlet composition...

still dun understand??? well its either ure not suitable for chemical engineering or ure plainly a CSTR!!!

still dun understand??? ive got nuthing more to say... just go figure it out urself...

which does not mean TUBERCULOSIS or TERRABYTE as i thought it was... its known actually as TINY BLADDER!!! ok i think u guys shd noe wad it means n how it shd be used... i shant say anything more...

XMA

i really cant exactly say how dis one came out... but it really helped us to understand Residence Time Distribution (RTD) for a Plug Flow Reactor (PFR)... i guess chem engineers shd noe dis... but if u dunno, lets just say that the supposed output distribution will follow input...

ok back to XMA... better known as Xinyi Marching Analogy, it uses the model of soldiers marching orderly through some given distance... if soldier A marches past the start point, he will take some time T to reach end point... likewise, soldier B will take the same time T to reach end point after crossing start point... so the time taken for all soldiers will be T... each soldier is different, and cross the start point at different times, so essentially, the pattern crossing the end point will be the same as that at the start point, with a time lag of T...

now we model the flow as the marching soldiers, the start and end points as the reactor boundaries, and the space time of the PFR as T... it can be shown tt output RTD will follow the input, with a delay of space time... yea

not a very easy concept, but if u blur, go gather a grp of ppl n march ard some big open area, n u'll noe wad i mean hahaha!!! (hopefully no army officers or warrants see dis, or i'll be darn remorseful for causing additional hurt for de poor soldiers currently suffering in army now haz)

and finally...

RTB

aka Return to Bed... which is wad im gonna do now...

tata!!!
