Data needs to be run for every minute, figured out how to run it for one minute...But not sure how to write a FOR loop for it.

I have a very large matrix of data, which I am analyzing minute by minute. For each minute's worth of data, I'm separating it by diameter intervals, to take weighted average velocities. At the end, I need to have two values for each minute's worth of data. I've pasted the chunk of code that I need to somehow integrate in to a for loop. I have 1771 minutes worth of data. In what I have pasted here, I was analyzing minute 200.
