[솔루션] 화공유체역학 3판 솔루션 (Fluid Mechanics For Chemical Engineers, 3rd Edition, Noel de Nevers) 솔루션입니다..!

총 챕터1 부터 20까지 구성되어 있습니다..^^

공부하는 저로써는.. 공부 할 때 정말 도움이 많이 됬던 자료 입니다. 수업을 따라가면서 이해 안가는 부분이 있으면 체크 하는 방식도 괜찮으며, 또 수업이 들은지 오래되어 다시 공부하고자 할때 도움이 되는 솔루션입니다..^^
그리고 시험기간에는 정말 없어서는 안될 자료이기도 하구요..^^
총1장부터 20장까지 구성되어있으며

챕터1의 한부분을 발췌했습니다..^^

Solutions Manual

Chapter 1 An * on a problem number means that the answer is given in Appendix D of the book.
_______________________________________________________________________
1.1 Laws Used, Newtons laws of motion, conservation of mass, first and second laws of thermodynamics. Laws Not Used, third law of thermodynamics, all electrostatic and magnetic laws, all laws discussing the behavior of matter at the atomic or subatomic level, all relativistic laws.

1.2 By ideal gas law, for uranium hexafluoride



Here the high density results from the high molecular weight.

At its normal boiling point, 4 K, by ideal gas law helium has



Here the high density results from the very low absolute temperature. The densities of other liquids with low values are: liquid methane at its nbp, 0.42 gm/cm3, acetylene at its nbp, 0.62, ethylene at its nbp, 0.57.

Discussion; the point of this problem is for the students to recognize that one of the principal differences between liquids and gases is the large difference in density. As a rule of thumb, the density of liquids is 1000 times that of gases.

1.3*



Discussion; this assumes no volume change on mixing. That is a good assumption here, and in many other cases. In a few, like ethanol and water have changes of up to a few %.

1.4 The maximum density of water occurs at 4°C, not at zero. The relation between the meter and the kg was defined to have the density of water at 4°C be 1.00 gm/cm3. However for various historical reasons it has ended up that the density of water at 4°C is about 0.99995 gm/cm3.

1.5*


Omitting the weight of the air makes a difference of 0.001 = 0.1%. This is normally ignored, but in the most careful work it must be considered.

1.6 This scale has the advantage that it
places a higher number on lower density
oils. That matches the price structure for
oil, where lower density crude oils have
a higher selling price, because they are
more easily converted to high-priced
products (e.g. gasoline). Oil prices will
often be quoted as (A + B*deg API) $/bbl.
where B ≈ $0.01/deg API.

The plot covers the whole range of petroleum liquids, from propane (s.g. ≈ 0.5) to asphalts (s.g. ≈ 1.1). Water (s.g. = 1) has 10° API.
