COMPUTER PROBLEM 1: Solution of the Colebrook-White equation via three different methods. Assigned on: Friday, January 13, 2012 Due on: Tuesday, January 24, 2012

Introduction The Moody diagram is the most reliable source of …show more content…
Start the iterations with an interval [0,0.1], and determine the number of iterations needed to achieve a tolerance of 10-2. To stop the computations, please compare two successive values of f , as follows: f j +1 − f j f j +1

100 < tolerance

2. Indicate the regimes to which the above points pertain (fully rough, smooth or transition), by determining where the points fall on the Moody chart. 3. Please, redo part 1. using the Newton-Raphson method. For this part, it is better to solve for X = 1 f (this will be your new variable; start from Eq. (2), not with Eq. (1), and re-arrange it in terms of X ) and then to back-calculate the resistance coefficient f for each iteration (this will ease the analytical determination of the derivative). As an initial guess, please start with f =0.05. Please, determine the number of iterations needed to achieve a tolerance of 10-2, defined in the same way as in point 1. 4. Compare your results in 1. and 3. with the explicit formula, proposed by Swammee and Jain (1976):

f =

0.25  − log10    ε 5.76    +  3.7 D (ℜ )0.9    

5. Please, redo part 1. using the fixed-point, or iteration- of-a-point method for the first five points in 1. Determine the number of iterations needed to achieve a convergence of 10-2, defined in the same way as in point 1. Start with a guessed value of f =0.05. 6. Please re-do computations of part 1., using tolerances of 10-1, 10-3, and 10-4. 7.

History and Ethics of Genetic Engineering By: The Late Dr. T.D. Singh on March 21, 2009, 7:40 a.m. Click to see larger image In 1966, B. Weiss and C.C. Richardson isolated DNA ligase, an enzyme that could be used to “ligate” or paste together two strands of DNA. Thus, researchers could now attach two or more DNA molecules or break it into fragments. In 1972, Paul Berg used restriction enzyme to cut DNA, and then a ligase to paste two DNA strands together to form a hybrid circular molecule…

Berry 1 Kyle Berry Cordray College Prep/ Reading March 17, 2015 GENETIC ENGINEERING FOR PERFECTION Genetic engineering is the process of manually adding new DNA to a living organism to add new traits that weren’t there before. The ethics of genetic engineering raises numerous questions whether it’s ethical or not. If genetic engineering could eliminate human imperfection would it be ethical? The perfect human would be disease free and have no “flaws”. Ralph Waldo Emerson was a transc…
