Today I got my first lab section in academic year 09/10. I woke up in a very morning or dawn instead. After a short bath, I went to school and attended the lab section full with excitement. I thought I was the earliest bird but Xinhui spoiled my plan. Haiz….
By the way, today experiment was all about the shell and tube heat exchanger. We were doing this to actually understand the theory of this heat exchanger and also to determine whether the parallel or countercurrent flow of water was more efficient.

This was the machine I dealed with in this morning. 
Basically, there were 7 stentless steel rods inside the cylinder which acted as the pine lines of hot water. Then cold water flowed outside these stentless steels rods. Heat exchange took place at here. This experiment was a very short experiment. After this experiment, me and my groupmate went to our school brand new canteen (actually opened at Jan) to have our blunch.
I ordered a Mutabak and I swear I won't ordered it again. There was not much filling inside. I really can't stand it...Shit.... I started miss Malaysian food...
