If you can please explain it in a few words which is right / wrong or in which book can I see to this topic

  • Calculate from how deep the bubble arrived.
  • Calculate how deep from the bubble arrived.
  • Calculate how deep the bubble arrived from.

None of these is well-phrased. I would write this as

Calculate the depth from which the bubble arrived.

or even better

Calculate the depth at which the bubble was released.

"Calculate from how deep" and "Calculate how deep from" are both ungrammatical formations.

  • Can I use here "from how deep" somehow? It makes sense, for me at least... – gladiator Apr 21 '19 at 12:45
  • @gladiator I don't see any way that "from how deep" can be used in a variant of the example sentence and be grammatically correct, or sound correct to a native spe4aker. It will probably be understood, but perceived as poor English. – David Siegel Apr 21 '19 at 13:46
