Problem 5.102

For the 180 elbow and nozzle flow shown in Fig. P5.102,determine the loss in available energy from section (1) to section(2). How much additional available energy is lost from section (2)to where the water comes to rest?

BSC2010 Lecture 3 Chapter 2 Cont’d – August 26, 2016 • Of all the chemical bonds, covalent bonds are the strongest • Macromolecules: large molecules formed by covalent linkages of smaller molecules • There are 4 kinds of macromolecules found in living organisms: proteins, carbohydrates, nucleic acids, and lipids • Polymers are broken in reactions caused by water • Condensation: the removal of water creates a covalent bond between monomers • Hydrolysis: the addition of water breaks a covalent bond between monomers • Carbohydrates: large molecules with similar compounds but differ in several properties • Oligosaccharides: composed of several monosaccharides • Polysaccharides: large polymers containing monosaccharides; the chains can be branching • Lipids: composed of hydrocarbons; insoluble in water because of the nonpolar covalent bonds • When close together, weak but additive van der Waals interactions hold them together. • Functions: stores energy, plays structural role in cell membranes, and thermal insulation • Triglycerides: fats are solid, and oils are liquid at room temperature; have very little polarity and are hydrophobic • They are made of fatty acids • Synthesis: 3 condensation reactions • Saturated fatty acids: bonds between carbon atoms are single; they are saturated with hydrogen • Unsaturated fatty acids: hydrocarbon chains contain one or more double bonds • Fatty acids are amphipathic: they have a hydrophilic head and a hydrophobic tail • It takes a lot of energy to break a chemical bond • The stronger the bond, the more energy is rele
