I have a 60 gal stand up air compressor that has a drain on the side about 5" up from the bottom. I open the valve and drain it regularly. My question is what about the area from the drain opening down? Is it designed to push all the water out of the opening or is there water below the valve?

There is no drain on the bottom? I have seen some odd things in my days, but I can’t believe any compressor manufacturer would use a tank with no drain at the lowest point. Are you sure someone didn’t just put a threaded plug into the bung at the bottom of the tank?
If not that is a really poor design because their 60 gallon tank effectively becomes a 50 gallon tank, as well as a dangerous design because it is now super prone to internal corrosion.

Unless the valve has U shaped pipe on the inside it's going to be leaving water in the tank.
Do you see a plug or bung on the bottom near the center?

If there isnt a drain on the bottom there is a hose on that valve inside the tank and it simply lays in the bottom. They did it to horizontal units too. These were designed to be able to be used in cold weather. The same as a factory petcock bottom drain. Ice forms in the bottom, no big deal, when it thaws out blow it out. Water didnt freeze in the ball valve up on side or top of the tank. Valve is never actually full of water.
