Materials Science Engineering - how much does it have to do Chemistry?

[ripemango]

<p>^ actually, its MatSE I’m looking into, not ChemE. And its not that I don’t want to major in chemistry, I first need to understand engineering better, because obviously, you can’t do much specifically related to engineering in high school.</p>

–Typical college general chemistry problem (acid-base equilibrium)</p>

<p>What is the hydronium ion concentration and pH of a 0.10 M solution of hypochlorous acid, Ka = 3.5 x 10-8?

College chem is that easy? That’s just AP level.</p>

A hot-air dryer is used to reduce the moisture content of 1500 kg/min of wet wood pulp from 0.75 kg H20/hg dry pulp to 0.15 wt% H20. Air is drawn from the atmosphere at 28 deg. C, 760 mmHg, and 50% relative humidity, sent through a blower-heater, and then fed to the dryer. The air leaves the dryer at 80 deg. C and 10 mm Hg (gauge). A sample of the exit air is drawn into a chamber containing a mirror and cooled slowly, keeping the guage pressure at 10 mm Hg. A mist is observed to form on the mirror at a temp of 40 deg. C. Calculate the mass of water removed from the pulp (Kg/min) and the volumetric flow rate of air entering the system (m^3/min).

Well I can’t really tell how difficult this problem would be, since I don’t know what kg/hg H20, wt%H20 or even relative humidity means.</p>
