 I don't completely understand your comment

> This requires me to use the convert function to convert degC to kelvin to get the Property functions to work.

Both these commands work, and give the same value of enthalpy

Property(massspecificenthalpy, T = 25*Unit(degC), P = 1.0 * Unit(atm), R717)

Property(massspecificenthalpy, T = 298.15*Unit(K), P = 1.0 * Unit(atm), R717)

@Mariusz Iwaniuk Did you extract the entire zip file to your hard drive?

In Windows Explorer, you should see something like this

The folders 0,1,2..9 contain the image files.

Reminds me of this application for calculating the cost of heating a home with natural gas

@acer Are you referring to the Polisario Controlled "Free Zone"?

Yes, that seems to be an glitch

When using units, I work in 2d math using Worksheet mode. This gives you

• the structure of input prompts
• the 2d math
• and the ability to use CTRL+Shift+U to enter units  (I find this quicker than using the mouse to choose units from the Units palette, and you don't see the Unit() syntax in your equations)

Load with(Units[Simple]) before you do any units calculations. The result of 10.0*Unit('ft')+6.0*Unit('inch') will automatically be converted to meters

Right click on the result and select "Units Formatting". In the dialog that pops up, enter ft^2 in "Custom Unit"

Mathcad has an elegant and simple implementation of units. I find that Mathcad users come to Maple with the same expectation of units.

We're working on a long term plan to bring make units handling more intuitive, and more deeply ingrained into the system. The first step was the introduction of the Units[Simple] package last year. Expect to see more changes with the next release.

@Markiyan Hirnyk Your screen shows shows "Adult literacy rate, population 15+ years, gender parity index (GPI)"

The application uses "Adult literacy rate, population 15+ years, both sexes (%)" for the year 2015. As the title of the application here states, only subsaharan african countries are plotted (as such, Egypt is not plotted)

@Markiyan Hirnyk The data comes from http://data.uis.unesco.org/Index.aspx?queryid=166. Specifically, it's the adult literacy rate for both sexes, ages 15+. The complete application is here

@Ramakrishnan The Organic Rankine Cycle application can be found here (and it's in the Application Gallery in Maple 2017). All the code is in the startup code region. In the application

• the flowchart is an image (that is, an image file created in another tool and placed on the plot with the background option)
• the text and numbers on the plot are textplots.

If you want box color to vary with the value of a variable, you'll need to construct the flowchart (i.e the boxes and the arrows) using plottools. Perhaps something like this

Please send one of your Mathcad worksheets to us at support@maplesoft.com (mark it for my attention)

I'll let you know if we think Maple is a viable alternative.
