Agas at 450 k is flowing in a 2-in steel pipe, schedule 40. the pipe is insulated with51 mm of lagging having a mean k=0.0623 w/m/k. the convective heat-transfer coefficient of the gas inside the pipe is 30.7 w/m2/k and the convective coefficient of air on the outside of the lagging is 10.8. the air is at a temperature 300k. calculate the heat loss per unit length of pipe, and overall heat transfer coefficient based on outside area.

honestly, school in itself just seems to be a huge waste of time. a lot of people graduate but still end up not doing anything in college anyways, which really makes the whole point of graduating seem useless. i'd rather not bring anyone's hopes up then. what i'd recommend is for whoever's reading this to simply drop out.

i mean, kanye did it. he said something along the lines of, "don't let society tell you what to do." now, he's obviously a very successful person, and since his album is called the college dropout i guess he never really had to go through all that nonsense in order to become a millionaire. the same goes for anyone else then.

yes, post it and i can try to you out.

i've read it so how can i ?

chapter i -- paris: september, 1792

a surging, seething, murmuring crowd of beings that are human only in name, for to the eye and ear they seem naught but savage creatures, animated by vile passions and by the lust of vengeance and of hate.

during the greater part of the day the guillotine had been kept busy at its ghastly work: all that france had boasted of in the past centuries, of ancient names, and blue blood, had paid toll to her desire for liberty and for fraternity.

hope this answer you: )!
