With the 40' rise I would use a 50/70 pressure switch instead of a 40/60. You will need a pump like a Goulds J5SH or a J15S that can build 80+ PSI to be able to use a 50/70 switch. But a 16 gallon pressure tank only holds about 3 gallons of water. You would be much better off controlling the pump with a PK1A-10 kit with a Cycle Stop Valve and a 10 gallon size tank. This will give you strong constant 60 PSI while you are using water and would do a better job than an 80 gallon size pressure tank.

I have access to a Berkeley 10SN for free. How does that compare to your the J5SH and J15S? Will it work?With the 40' rise I would use a 50/70 pressure switch instead of a 40/60.

Custom PK1A PSIDE-KICK Pressure Tank Kit
Replaces large pressure tanks. Preset and easy to install for the DIY customer. The pside-kick kit is a complete constant pressure control package for most pump systems with demands from 1 to 25 gpm. This kit comes with everything you see and utilizes a mechanical pressure switch.
https://www.pentair.com/content/dam/extranet/web/nam/berkeley/data-sheets/sn-series-sell-sheet.pdf has the curves. It is a higher volume lower pressure pump, but might still do an adequate job. It is not going to be usable with a 50/70 pressure switch.
Great, thanks! I assume I should go for the 10 gallon tank instead of the 4.5?
Won't help much at 40/60. But if you ever replace the pump and want 50/70 the 10 gallon tank would be best.
