Turbulent (FLASHBACK IV)

We Never missed Manufacturing Process class in third sem , the obvious reason being Prof. Moolchandani. That and fact that the class was at noon and we finally woked up by then. Prof. Moolchandani was different form the other , he was 20 years younger than the other profs. Not more than 35 , he usually wore t- shirts and jeans which displayed his US university logo. He had like 5 degrees from world’s top 5 universities- MIT , Corneel , Princeton , IIT etc. and he wore T-shirt form all of them. He usually caries Walkman along with him and put them on after the class get over. Senior told that professor Moolchandani was not supposed to be taking a full course so early However the professor he was assisting expired and he had to take full course .
“Hello everyone” Prof Moolchandani said , as he entered , he offered chewing gum to the first row students. The front row guys were all muggers and freaked out at the offer. They declined and he shrugged and popped a piece in his mouth and turned out to the board. “Turbulent Flows” he wrote on the capital letters on the board. “ Guys in the first five ;lectures , we studied simple flows called out laminar flows. The shape and direction of these flows are predictable with the help of formulas and equations . You know which equation right ?” He looked around for answers , unlike other professors he don’t stick to the front row students. In fact he scavenged at the back.
“Okay , I’m not asking this to studious kids of the front , its meant for the cool dudes of the back. Rohit and me were chronic back benchers , these were most defensive position for guys like us.
“Rohit , tell me which is first principle equation for laminar flows?”
“Sir , me” rohit surprised , that professor would know his name .
“Yes you , rohit. Iknow you know the answer”
“The Navier-strokes equation” Rohit said surprising himself.
“Right , you want to write it down for the class”
Rohit ran up the board and the front benchers in the front row smirked at a backbencher contributing to the class. Equation was right , rohit won’t go to the blackboard unless until he knew the equation was right.
Rohit came back and sat between me and ashok, hi sbody language suggesting as if he has conquered mount everest or has just landed on the earth after visit from moon.
“Perfect rohit , thanks , by the way was it you and avinash who wrote the impact of lubricant efficiency on bike fuel consumption in your last term paper” professor asked.
“Yes sir, Me and avinash id that , not accurately though” Rohit said proudly.
“I liked that , by the way what went wrong in the project avinash” Prof asked , turning his eyes towards me.
“The heat generated by the piston and crank was too high to be resisted by the lubricant with low octave levels , sir” I explained .
“So, why you didn’t tried lubricant with high octave level?” Prof . asked
“we tried , but hydrocarbon also increased putting extra pressure on the exhaustive valve.” I answered.
“How about removing same sloth to reduce pressure on exhaustive valve. And probably increasing the efficiency of engine”- professor asked.
“Sir , but that would produce lots of sounds”- I said.
“Why we can’t try the synthetic muffler in spite of the Iron ore” prof said
“Yes sir” I got my answer
“So you can do it now” Prof said
“Yes sir” I said
“Try it out” Prof said.
“sure sir” said.
