Extending the Thermodynamic Functions To Their Full Range: Functions vs. Pressure

While finishing up the process of generating the plots of the thermodynamic functions vs. pressure I found an issue with how plots are drawn on the x-axis when the x-axis has a logarithmic scale. I calculated numeric values for every … Continue reading

Extending the Thermodynamic Functions To Their Full Range

Today I extended all 24 functions to their full range, 0-705.44 °F and 0.08866-3203.6 psi. I’ve shown the functions vs. temperature; the functions vs. pressure are generally derived from the same lines in the steam tables so the only difference … Continue reading

Fixing the Thermodynamic Functions for Saturated Water As A Function of Temperature

I’ve updated five of the thermodynamic property functions vs. temperature. Note that most of these define properties only up to a bit above 600 °F and, more importantly, to 1800 psi. The values for saturated water are defined up to … Continue reading

Testing the Thermodynamic Functions for Saturated Water As A Function of Pressure

I was getting ready to do new curve fits on all the segments of the thermodynamic functions that seemed to require it. However, I realized that I hadn’t yet plotted them all out as a function of pressure since I … Continue reading

Testing the Thermodynamic Functions for Saturated Water As A Function of Pressure–Except…

I started working through the graphs of the various thermodynamic functions vs. pressure and recognized that the standard format wasn’t showing all of the detail contained in the fits across the different ranges of input pressure. If the plotable width … Continue reading

Testing the Thermodynamic Functions for Saturated Water As A Function of Temperature

Here are plots of the standard thermodynamic values for saturated water, all as a function of temperature. Tomorrow I’ll plot them all out as a function of pressure. I extended the range of each function below 32 degrees Fahrenheit to … Continue reading

Steam Tables (and Thermodynamic Properties of Fluids In General)

A little while ago I was ruminating on the subject of needing to know the thermodynamic properties of materials before you could do simulations of those materials. I therefore figured I’d spend the week dusting off some old functions I’d … Continue reading

All Solutions Are Iterative

I’ve spilled a lot of wind and electrons talking and writing about iteration as a path to solving problems, in a business analysis context and elsewhere. My framework incorporates multiple levels of iteration, of course, but through earning and maintaining … Continue reading

Functional Decomposition

My first engineering job was as a process engineer in the paper industry, where I designed and analyzed large industrial systems that ran this… through this… to make this… We can break the system down (or build it up) like … Continue reading

Using Data In My Framework and In Simulations

I recently wrote about how data is collected and used in the different phases of my business analysis framework. After giving the most recent version of my presentation on the subject I was asked for clarification about how the data … Continue reading
