And can anyone provide information on how to carry out the integration for Kr using the Fredlund and Xing model? The reason for this is that I am getting a negative Kr at any suction pressure higher than the suction at the inflection point I used and I have checked through without seeing anything wrong with my computation.
Hi Johnson,
Did you apply an analytical integration or a numerical one?
Hence do you have a function which you can integrate, or do you only have measurements of the function you want to integrate? Makes quite a difference on the answer to be given.
Cheers,
Frank
Thank you sir. I am applying numerical integration using measurements of the function to be integrated. Thank you sir for your concern.
Hi there Johnson,
Call me Frank will you?
When you are apllying numerical integration, an algorithm which is easy to implement on numerical datatsets is Simpons rule. See the details at:
http://en.wikipedia.org/wiki/Simpson's_rule
Try it out. You can easily program it using a spreadsheet.
Cheers,
Frank
Thank you sir. I will try that and feed you back. But sir permit me to add Prof. to Frank because you are my elder.
