Hi, I need some help, I must solve the following nonlinear differential equation, -k1*(c'') = -k2*(c^0.5) - u*(c') subject to the bc, u*(c - 0.5) = k1*(c') where k1, k2, and u are constants, thanks

I need to know the cost of a compressor that can be used to compress 59 kg/h methane from 1 atm to 25 atm. The work required by the compressor is 9.36 kW. Any idea where i can find the cost of compressors?

because i thought it was appropriate, there is even a better approximator than Newtons method. we have x^2 = 150 an educated guess would be to choose x = 12 transform the eqn, x^2 = xy = 150, just as the poster did above. then y = 12.5 if x = 12 now, take the partial derivative of xy...

psychometric charts are certainly mad, although they are really useful when calculating humidities.

Can anybody post a link for the steam tables of water? Any would work that have specific volumes of the gas and liquid phases at all temperatures, and also have the specific enthalpies of each phase at each temperature. thanks.

Its funny, however, that sometimes epiphanies in science beg for higher mathematics.

thats a nice package, a double in physics and electrical engineering.

well, some of the calculations in engineering get pretty lengthy, and accuracy is a must. There are plenty of smart people out there, but if they can't produce the right numbers, it will be very hard. I know this from my experience in chemical engineering courses. This is probably more...

i still want to be a mathematician

you'll be doing lots of PDE's in chemical engineering, and there are a ton of graphs to use (though may be familiar, the psychrometric chart). I love problem solving and every minute of cheme! EE's come across Fourier analysis, and perhaps unfamiliar to some, laplace transforms.

Hello there, Im a chemical engineering major, and i need some help writing a resume for internships. Is there any good format that i should follow? Do i have to write an essay? List of references? thanks,

i like engineering because its very mathematical.

I'm actually just the opposite, i like doing proofs but it takes a lot out of me to read some one else's.

i know how to program, and i use it when it deems useful. I just kinda picked programming up.

how do we know that the sqrt of i can be denoted as a+bi?
