I make it a habit never to mix water-based with oil-based, way to many problems occure. On the up note they have water-based poly, use that. Good-Luck
You can apply "oil" based polyurethane over "oil" based enamel, you can also apply "water" based polyurethane over "water" based enamel, never mix the two, there's to much of a chance for problems.
Yes, as long as the polyurethane is oil-based.
Yes, both oil and water-based polyurethanes will adhere well to an item coated with acrylic paint. If it is a polyurethane paint, dull the surface prior to painting. If it is a clear. realize that that oil based polyurethane will impart an amber hue while a water based polyurethane is crystal clear and will not affect the color.
No. Poly and paint are incompatible. Instead use liquid floor wax. It's easier to work with and will give you a longer lasting surface that doesn't stick to paPer when wet. You can continue to re coat for maintenance. Great for tabletops shelves or painted floors.
Polyurethane will give a long lasting easy to apply finish. Use a water based polyurethane ans clean up will be much easier. You should get years of wear from a good polyurethane finish.
Yes, it can. I would sand it with a 220 or even 360 grit.
Yes, you can.

Melting of Antarctica's ice shelves occurs underwater, based on warming ocean water. which melts the shelves from underneath. This phenomenon occurs all year and is not limited to summer.
PU stands for Polyurethane, a kind of plastic that's the main ingredient in the paint.
It isn't so much the type of paint, its the finish on the paint, you want a tough durable finish for a Bangle. TIP: if you use a oil based enamel, use a oil based polyurethane finish, if you use a water based enamel, use a water based polyurethane, Make it a rule of thumb and you will never have bubbling or peeling problems.
Polyurethane comes in two forms, oil-based or water-based. Both are quite durable. Oil-based poly is slightly amber or golden-colored, so it will give a golden glow to your wood. Water-based poly dries crystal-clear so it won't change the color of your floors at all. There are some oil-modified versions of polyurethane on the market now, available to consumers, which are still soap-and-water clean-up like water-based polys. These oil-modified polys tend to be more durable than ordinary polyurethane. To minimize the appearance of scratches and wear later, choose a satin-finish instead of gloss.
