Hi there,
I'm new here and what really suprised me was the fact that registration on this forum was very easy and quick, thanks to admins for that!
I've been working on some heat transfer correlations for Nusselt criterial number in convection, and what apppeared... that some corelations depends on visocity of fluid by the wall, like Sider-Tate's correlation or Hausen's.
I decided to build a program that will obtain the temperatures by the wall in 73 different conditions using the Sider-Tate correlation combined with the equation for heat flux and with equation for convective heat transfer coef.(Nu).
Namely I got 73 different Reynolds numbers, length of pipe, diameters and heat transfer surfaces placed in arrays.
The method to find a root for this combined equation is by spliting the interval, where the function of this equation is needed. However the function depends on the array, cos there are the parameters needed to by given from the array. So the function name need to have array index, but when i create it, it responds with "the functon must be named", when i resign, the for loop doesnt work.
I described it more clearly in the document.
I would be grateful if u could solve the problem
Thanks in advance
Lucas
