Default RO "Residual Dead Volume" and "Dead Volume"

I'm trying to complete the application for organic certification in Ontario and the application asks for the above numbers for my RO.
Since I built the machine myself, I can't ask the manufacturer for the numbers and Google hasn't been any help either.
I have a single membrane XLE 4040 in a stainless housing with a 10" cartridge filter, a feed pump and a high pressure pump. I'm guessing I might also need to know the length of the piping in the unit. If so, I will measure that this weekend.
Can anyone tell me how to calculate the "Residual Dead Volume" and "Dead Volume" myself please?
Thanks
Steve

I have never heard those terms.

The numbers are connected to the amount of permeate that must be used as a rinse after a wash.
