"Amazing site you have."

"I'm writing for you because since more than 4 years, my father and I, have been using the thermodynamics software, and let me thank for the quality, the knowledge, etc, etc, I love it, we love it!.

Now I need to ask you how can we acquire the CD, the Professional Edition? It would be better for us. I hope that you can help me."

"With the growing problems of today around our planet that are attributed to
Global Warming and our depleting Energy resources, it is essential that our
Scientists, and Engineers have the most optimum tools available to them for
the facilitation of their important work.  It is also just as important
that Thermodynamic Students can access the same tools for the support of
their education.  Thermofluids.net (TEST) provides these much needed tools.
Thank You for your extended effort in creating the best thermodynamic
software and virtual educator that I have experienced."

"Congratulations on the great work. Your software is about as easy to use as I can foresee. I wish I had this when I took thermodynamics."

"Outstanding! Fantastic!  Beautiful! Congratulations"

"When I access this program from home, I\'m delighted with the results.  Unlike so many applications, the interface is immediately obvious for a first-time user. "

"Thank you for a very good and easy to understand program."

"Seen your site and liked your software for thermal science."

"I wish to thank you for creating a very useful software tool and making it available to me."

"Way cool. Great job. Thanks for making something so useful available to hobbyist like me. "

"I am excited about your Web-based Thermodynamic Software....Would you design some animations with daemons which explain how to operate a fuel fired steam boiler efficiently and economically? "

"This site is wonderful for studying thermodynamics for professionals who have left behind academics "

" I was very impressed with the slides on the TEST web page which
so clearly depict the power cycles. "

" Great job! I' will recommend your TEST to everybody."

" This software is better!!!!!!! I\'ve been using your program online for several months and find that it\'s really a good and powerful program.\" "

" your program is a comprehensive  program "

" While surfing the net, I came across this site, and I think its great!! I just wanted to let you know that."

" es fabuloso "

" I really like your TEST software..."

"I just received your book on the subject above that I've ordered at the same time with your software CD from Amazon.com. The book is just as interesting as learning and using the software at your on-line site during the last one or two years was. "

" I want to thank you for making available an economical program that models Thermodynamics. I used you web version of test for quite some time before purchasing the CD. I have been working on a turbo shaft engine which utilizes ejector ramjets as the gas generator. It has been extremely helpful in modeling the system."

"I have found your beautiful software by chance the other day!"

"I must say that I am impressed 110% with what you've made available here, I searched endlessly for a calculator that would give me answer's to a couple of question's and what I did find was painful to use at best, the example's and picture's clear up a lot question's as you work through the equation's & problem's. Well done! "

"Great Software!"

"I have good references about your software, so I would like to know more about it. have heard about \"TEST\" System, and I think it´s an excellent system for beginners like me. I´m Chemical Engineer, but I don´t have enough experience in software for simulation."

"Bless You!!!"

"Saludos, es una interesante herramienta. "

"I was thoroughly impressed with your software!"

"Very nicely done! Thanks!"

"TEST,it's a cool idea and so useful!!"

"Thank you for your wonderful thermodynamics program!"

"Thank you, your software is very impressive, I wish I would have had it when I was in college!"

"Your software is truly a very helpful aid in visualizing some intricate thermodynamics concepts and simplifies the calculation process (with the daemons). Thanks and more power! "

"It is nice because it is so easy to use. I do not need a PhD. to use it. "

"Excellent educational tool."

"Amazing to work with. Saves a lot of time and is error free. Thanks!"

"I have had a lot of your 'EXCELLENT-EXCELLENT' applets online in various Centers for well over 4 years!"

"The TEST Software is impressive and it contains a wealth of thermodynamic knowledge. It is easy to use to solve complex problems."

"I love your program. I'm curious, however, why you only allow masses in specifying quantities."

"You are very cool!"

"Many, Many thanks for the publication of such an excellent study aid."

"I shall be linking your wonderful educative R-12 visual calculator on http://hvacindia.com , a fledgling non-profit HVAC web portal 
promoted by the Indian Society of Heating, Refrigerating and Air Conditioning, Mumbai Chapter, an associate of ASHRAE.

It was a joy to see that the most interesting calculator I have seen is from kgp!"

"I browsed AltaVista for a Psychrometric Table and I found this most amazing and useful tool for which you deserve the warmest congratulations. I can hardly wait to test all the features..."

"TEST.....what a great/cool idea!"

"Your calculator is a life saver."

"This sight is completely awesome.  I have spent much of my career working with supercritical and near critical fluids, and have always struggled to find the correct table or chart to give me an idea of what to expect at a given pressure, temperature, or specific volume.  Your daemons seem to solve many of my problems.  Right now I am working with a single phase system (which is much simpler than binary or worse systems) and the points I have checked seem accurate."

"TEST appears to be very comprehensive in its treatment of thermodynamic problems."

"Kudos!"

"I am very impressed with the capabilities of your collection in TEST..."

"I find on your Homepage a cool java applet to calculate the properties of R134a..."

"A very resourceful idea for a site..."

"Your overall system looks very useful and exceptionally flexible.
For many of the subsystem modeling questions that I am thinking of,
it will make my investigations much easier, doubtless more reliable,
and incredibly much faster than I had reasonable expectations of
finding. Your stuff is particularly attractive for some things I need to model, e.g. air conditioning, e.g.."

"It's Sunday afternoon, daffodils out, fitful showers, fresh air, I'm registering our website, and came across yours. It is like a refreshing breeze. I'm interested in putting a link on our site to yours. Are you game?"
