This video shows how you can solve a simple piping network in EES (Engineering Equation Solver). Something that needs to be done by iteration only to get the exact solution. This video shows the complete solution of Example 8-8 (internal flow) from Cengel & Cimbala 's Fluid Mechanics 4th Edition. It also shows a couple of clever techniques on how to solve problems numerically. Friction factors are calculated exactly in every branch and from there the flow rate in every branch can be calculated.

I am enjoying your videos, and working on doing some of my own. EES has come a long way since the late 90s, when I started using it (on a Mac!). Three comments: 1. No need to define “g” in your “Givens” as it is a defined constant in EES; 2. You forgot to comment back in the f_1 and f_2 variables after you adjusted the minimum and maximum values; and, 3. Your video of you sometimes covers information to which you are referring on the computer screen. Overall, excellent and helpful videos. (I am an Assistant Professor of Marine Engineering at the United States Merchant Marine Academy, and am a USCG Licensed Chief Engineer (retired from sailing, but license is still active).

Thanks for your comment. Appreciate it. 1- I didn't use g# (the predefined constant in EES) because in the formatted equation window I prefer to see "g" instead of "9.807 m/s2". However, thanks for mentioning it. 2- I shouldn't comment f_1 and f_1 back in because I uncommented the Colebrook equation for them in the code. 3- I noticed that as a problem and eventually I came up with a solution which I will apply to future videos. One more time, thanks for your comment and I appreciate the time you took to watch the video and comment.

@@professorbehrang cool. I prefer g to show up in formatted equations, too, so I usually put 'g=g#' in the equations window and that is my workaround.

I watched this video for fun today I miss school and i miss you

You miss the thing that you wanted to be done with the most?! Classic. I will upload more videos this Summer to keep you busy.

Hello, great video! Is there a reason why you don't use the code f_1=moodychart(Re_1;Epsilon) To simply let EES solve your RE values?

@professorbehrang Год назад

Thanks. I didn’t know that function existed in EES!

@danielvasquez5237 Год назад

Hi there . Why didn't you consider the loss in the tess, from point 1 for example?

@professorbehrang Год назад

You guess what the problem statement said was the equivalent pipe length but that can be double checked. Also, in this problem since the lengths are big, major losses are bigger than minor losses. Therefore, another approach would be to ignore minor losses compared to major losses.

Hi Mr. Professor! Thank you for your useful videos. I don't know how to write exp(....) and ln(...) on EES. Could you please help me? From where can i learn writing these

@professorbehrang 9 месяцев назад

both functions are exp() and ln() and they do work in EES. What's the problem?

@orhansahmerdan8978 9 месяцев назад

Sorry Sir! I thought ln(...) may be written like "naturallogaritma" and exp(...) may be written like "e^". But, after asking you this question, i realized that how to write functions is shown in "function info" part of the ees. So now, there is no problem. Thank you for your help.
