redargon: Here is an MS Excel sample case dealing with combustion. If you have any questions, please let me know. Thanks, Gordan

minger: I do appreciate your input. With all the respect to other people expressing their views and preferences, it makes me feel somehow better now -- I am not the only one with this kind of thinking ... Thanks, Gordan

To All: Apparently, being engineers and practicing engineering for many, many years, there are different views and opinions on the same subject matter. Therefore, please do it as it suits your preferences and ways of doing business. Thanks, Gordan

caslav.ilic: I do appreciate your reply and rational. Thanks, Gordan

Mech Engineer: I do appreciate your reply and rational. Thanks, Gordan

Mech Engineer: You should be encouraging people to do some work on their own instead of saying there is a black box and let's go with the black box -- that is not a good engineering approach ... In my opinion, people should try something on their own no matter what the problem scope is. For...

Hi there: Yes, you are right. But here is the catch. With MS Office, either BASIC or VBA come for free. MS Excel provides easy environment to work with and files are very small. Today, everybody has a copy of MS Excel on his/her computer. Therfore, files can be exchanged quickly...

FrogPad: Actually, it is possible to use MS Excel for Euler integration etc. It get clumsy, but it is possible. One neds to use BASIC or VBA by creating functions/subroutines. Such routines are connected to cells in a sheet. By playing with cells and routines, solution is possible...

To All: I have been practicing engineering for a while. Also, I have been dealing with programming for a number of years. Way back, programming started with Fortan and BASIC. In my opinion, if one knows one programming language very well, there is no need to fear any new/other language. I...

shamrock5585: Thank you very much for your positive and negative feedback to my input. As long as the concept is self sustainable and generates revenues, I just do not understand what the "expensive project" atribute has to do with the concept and/or idea that solves and/or brings to the...

To All: Even though this ongoing thread was started long time ago, I just noticed it. Therefore, I would like to share some of my thoughts on this interesting subject matter. I do believe in the energy mix as a way to move forward. I would start by using proven technologies and then...

Hi there: In terms of the thermal efficiency definition, nothing changes. Give a try and see what happens. In my opinion, there should be no major changes for low pressure values in terms of the operating conditions and final numeric values. However, as you indicated, the equations get...

Hi there: If you are doing steam calculations, just go with the steam tables. If you are doing combustion calculations, then it is another story. In general, it would be enthalpy of formation for water. Now you have to be careful. This is tricky. For low pressure combustion...

Hi there: Here is a URL that might help you with required thrust and fuel consumption calculations: http://engware.i-dentity.com/calc3.htm Thanks, Gordan
