Justification For problem 6.118, I used rho and mu for water at 20˚C from Table A.3. Also, epsilon denoted in the code is actually .04/12 which equals .003333333. Flow rate is known, thus I implemented the second block of equations in the code to find values for V_i, Re_i, and f_i. Next, I knew that pipes 1,2, and 3 are in parallel and have equal head loss, so I equated h_f1, h_f2, and h_f3. Similarly, flow rates in the parallel pipes must equal the initial flow rate, so I equated these values as well (Q_1, Q_2, Q_3, and Q_i). Subsequently, using L, V, and D for each pipe, EES guesses values for f and, using the

Unformatted text preview: equations for Q, h_f, Re, and f_1, finds DELTAPy and DELTAPx. Finally, these pressure drops are summed to find the total pressure drop. Before executing the equations variable limits must be set. F, h_f, Q, Re, and V all must be positive, so a lower limit of zero must be set for these values. Also, as in example 114 of the program, an upper limit of 0.1 is set for f values in order to limit guesses and allow convergence. Overall, EES is fairly simple to use and, aside from the decreased functionality of the student edition of the program, the program seems to be applicable and helpful to many aspects of undergraduate engineering problem solving v...
