Mathcad help finding variable value
(OP)
I have a set of results from a simulation, in the form of a velocity along with the corresponding distance from the pipe centre. There are about 20 points.
I also have an equation that tries to model this, so i can enter in the same distances from the pipe centre and i want the output to be as close as possible to the simulation velocities.
To do this i have added some variables (at the moment 1 ("b") but i may progress to have 2 variables) to my formula which i wish mathcad to define for me...
How do i go about this, i have tried but, very, unsuccessful
Thanks in advance,

If I can puzzle out where you started, it looks like
"d" is density and if I assume water, then it is in kg/m^3
"v" is viscosity (I'll assume 20C) in N*s/m^2
"R" is radius and I'll guess it is in m
"Vm" by process of eliminiation it must be mean velocity in m/s
Those assumptions get to the Reynolds Number you calculated.
Given that, I couldn't get the solve block to converge. Why are you trying to use "find" instead of "genfit"? I don't think that MathCad will do a "find" with an imbeded array.

That answer gives you a different "b" for every "r". He's looking for a single "b" that generates a data set that matches "v".
