    Okay now Waste management, where sewage water as well as human feces get treated. There are alot of Bio and Chemistry stuff to it, but i dont see the "Physics" in it at all.

    Can anyone tell me any "physics" that gets involved in the waste treatment processes??

    thank you

    Biology is chemistry is physics. And water, amongst other thing's, run's downhill according to gravity which is physics.

    thank you for that, but seriously you think i didnt know that??
    i mean more of the supplementary material such as physics in aeration etc...

    yes.....

    I wrote a paper on the patrons of the London sewage project for one of my engineering courses. Joesph Bazelgette was the engineer. the main (Victorian) london sewers run with the flow of gravity to two points (Abbey Mills) and (Dartford); from there they are pumped up to a level where gravity can then take over again (there are pumping stations at the two sites) - the sewege is then pumped into the thames estury, beyond the point where it would be an issue.

    gravity = physics.
    The hand of time rested on the half-hour mark, and all along that old front line of the English there came a whistling and a crying. The men of the first wave climbed up the parapets, in tumult, darkness, and the presence of death, and having done with all pleasant things, advanced across No Man's Land to begin the Battle of the Somme. - Poet John Masefield.

    fluid mechanics
    Yes Dr.Rocket, i had this in mind, i was trying to write on the dynamics at which air flows in an aeration plant, and not to mention heat transfer etc... but if i use mathematical notations of Fluid dynamics, which requires multivariable calculus, specifically vector calculus, our teachers wont be very happy at all, as they might think im just showing off....., and again if i dont write mathematical notations, and just use words, i think i might not exactly describe the process as precisely. Of course i dont have to use MV calculus, can just use simple SV Calculus but again our Physics teachers are assuming we have no thorough knowledge of Calculus hence seeing any student using calculus will be looked throughly again and again. I dont have any problem with that because im pretty familiar with SV calculus, and can explain the process which im heading. Maybe i should just stick with words, and simple forumlas like the Gas laws............

    what do you think?
