Today I chatted with a university scuba student about the current "Cascade Storage Banks" VDH thread. She asked how someone would design a cascade system "adequate for her needs." I told her that once she made certain simple assumptions about capacity, usage, etc., then doing so is straightforward, but she absolutely would need to know how to compute the tank pressures resulting after a scuba cylinder is equalized with a cascade cylinder.

I stepped her through a quick equalization example, and then, to see if she really understands, I challenged her to spec out an "adequate" cascade system using some realistic conditions/assumptions I gave her. No internet "help" allowed! Excel spreadsheet calculations permissible, though she must explain them to me.

She took the bait!

If there is interest here, I will post her solution when it's available.
