She's still going to drown for an obvious reason...
Ok, I give up, what's the reason? The tube's diameter seems large enough to let her breath through it for a while without tiring.
Btw, if I were in this situation I might try to move my body back and forth to spill enough water so I can maybe bring my nose above the surface. Furthermore, there is a drain-stopper she might be able to dislodge.

It's pretty wide, also pretty long. She must have to completely fill and empty her lungs with each breath to get even a little fresh air through it. Also she's pretty deep. You can't breathe through a snorkel except right at the surface. She would be fighting against a pressure difference of at least 1 pound per square inch every time she tries to inflate her lungs. Water would probably leak in through her nose instead. If not, she'd still tire fast.

She can just breath out through her nose and breath in with her mouth. That way she will always have fresh air. I don't know anything about snorkeling but she's not *that* deep. If I can suck up air into my lung while standing neck-deep in water (effortlessly), then it should be possible to breath in this position, too. Right?

At bathtub depth, I have my serious doubts that the pressure would mean anything. Its comparable to standard snorkeling depth, which is really shallow (plus the diaphragm is a really strong muscle). As for the estimated one PSI of water pressure ... that's basically ignorable, since air pressure at sea level is 14.7 PSI.
