I can see your logic but this does not seem to work. Supposing sucessive iterations were x1=99, x2=100, x3=101 then xx = -1/0
I also tried with some actual data. My first three iterations were 799,717,642 using my current method it converges at 577. The formula gives xx as -198 as these are...
I have a complex mathematical model (about 2000 lines of code) which calculates heat exchanger performance.
Using Q=UxAxLMTD I want to iterate the entering temperature until I find that the installed surface satisfies a target duty.
At present I
1 guess an entering temperature and from...
