Using the formula from the Handbook of Model Rocketry by G. Harry Stine, i started by writing down all the variables, then a simple "plug & chug" to the finish...

sounds simple, but it took me a couple hours due to constant interruptions during critical mathematical operations.

i finally came up with a reasonable answer after the third re-check of my work.

it was a nice exercise in rocket science.
