Using solver to solve contraint with varying parameter

I am attempting my first non-trivial mathcad worksheet, and i am a little stuck.

I am trying solve a problem where my solve block constraints vary with time. I would like plot the result of the solve block as a function of time. It appears that the solve block will not support this. Can someone please help me figure out a better strategy.

The attached worksheet is a sample worksheet that demonstrates what I am trying to accomplish. My actual worksheet is on a different machine that I am not permitted to remove files from.

Two problems: 1. You need to give Pd units of pressure (psi presumably). 2. You need to supply an initial guess for r just before "Given", say r = ro.
