EES will be used throughout the course as an aid for solving equations, plotting trends, etc. Students should become familiar with either EES or some similar mathematical equation solving program (Mathcad, Matlab, etc.).

EES is installed on the MNE PCStudio computers in Reber Building.

** To get an account on these computers, fill out a form outside of room 224 Reber. **

Your own personal copy of EES can be downloaded * for free* from Penn State's
Angel website . Here are instructions for installing EES on your computer.

Useful_tips_for_copying_EES_to_Word_and_Excel.pdf - This is a pdf file with instructions on how to copy table data and plots from EES into Excel or Word.

Here are some EES example files that you may download. To download and use:

- Click on the desired file.
- Depending on your browser, whether from a Windows or a linux machine, and how it is configured, it will either launch EES or prompt you as to whether you wish to open the file or save it.
- If EES is loaded on your machine, choose the option to open the file. (You may have to browse to find the correct application.)
- If EES is not loaded on your machine, choose the option to save the file.
- Right-clicking on the file name works best on some browsers.

- Sample_simple_set_of_simultaneous_equations.EES
- A simple application of EES to solve a set of three simultaneous equations.

See also Sample_simple_set_of_simultaneous_equations.pdf - images of the EES windows for this example problem. - Moody_chart_solver_Colebrook_equation.EES
- A simple application of EES to solve the Colebrook equation for
friction factor
*f*as a function of Reynolds number and nondimensional roughness coefficient. This one works only for fully developed turbulent pipe flow. - Moody_chart_solver_MoodyChart_subroutine.EES
- A simple application of EES to solve the for friction factor
*f*as a function of Reynolds number and nondimensional roughness coefficient. This version used a built-in subroutine called MoodyChart, and it works for both laminar and turbulent fully developed pipe flow. - Example_minor_losses.EES - EES solution to the minor loss example discussed in class - this problem shows how to use EES to solve a set of simultaneous equations involving major and minor losses.
- Example_matching_pump_to_pipe_system.EES - EES solution to the pump example discussed in class - this problem shows how to use EES to match a pump supply curve to a piping system demand curve.
- Example_matching_pump_to_pipe_system_with_plots.EES - EES solution to the pump example discussed in class - this problem shows how to use EES to plot a pump supply curve and a piping system demand curve, including the plot.
- Example_08_09_toilet_flushing_part_a.EES - EES solution to Example Problem 8-9 in the text - the toilet flushing problem, Part (a).
- Example_08_09_toilet_flushing_part_b.EES - EES solution to Example Problem 8-9 in the text - the toilet flushing problem, Part (b).
- Pump_bypass_example_problem.EES - EES solution to the pump bypass example discussed in class - this problem involves a parallel piping network.
