In a pipe heat exchanger, crude oil on 30 ℃ is used to cool the heavy oil from 180℃ to 120℃.Mass flow of heavy oil is Wh=104kg / h，and crude oil respectively Wc=1.3×104kg/h. Specific heat, respectively is Cph=2.2 kJ/(kg•℃), Cpc=1.9 kJ/(kg•℃). Overall heat transfer coefficient K=120W/(m2•K). Try to calculate the required heat transfer area for parallel flow and countercurrent flow.

A 2.00 mole sample of a perfect gas is heated from 41.2L and 255K to 42.2 L and 317K against a constant external pressure of 1.00 bar. What is delta H, delta U, q, and w for this process? (initial ---> intermediate---> final state). Intermediate state is V=41.2L, T=317K
Hint: first calculate delta h, delta u, q, and w for each arm. (Initial to intermediate being one arm, then intermediate to final being second arm)

Water, hydrogen sulfide and selenium hydride are three similar molecules, but only one is the solvent of life. With reference to their chemical structure and the associated intermolecular forces, describe the molecular basis for some of the analous properties of liquid water and explain the significance of this with reference to H bonding, Coulumbic and Hydrophobic interaction IN BIOMOLECULES??
Hey guys if anyone can help, I would appreciate. I actually figure H bonding but Coulumbic and Hydrophobic i am having a lot of trouble.

A wet solid is dried from 40% to 10% moisture under
constant drying conditions in 5 hours. If
the equilibrium moisture content is 0.0416 kg moisture/kg dry solid
and the critical moisture
content is 14%, how long will it take to dry from 40% to 5%
moisture under the same conditions.
All percentages other than equilibrium moisture content are on wet
basis. Assume linear relation
between rate of drying and moisture content during falling rate

. A 0.65 specific gravity natural gas contains 10% nitrogen, 8% carbon dioxide, and 2% hydrogen sulfide. Brill and Beggs correlation can used in estimating the z-factor values accurately enough for many engineering calculations. Brill and Beggs’ z-factor correlation is expressed as follows: With your knowledge in computer literacy and information technology coupled with Matlab programming, develop either a Microsoft excel spreadsheet program or a Matlab script to compute the z-factor of the gas at initial pressure and temperature of 5,000 psia and 180 °F respectively. Your application should be able to compute the z-factor for the gas at varying temperature and pressure.
