Vyutakrama Kapalbhati:
1. In place of air, draw water through the nostrils and expel it through the mouth.
Sheetakrama Kapalbhati:

      An additional type of Kapalbhati involves inhaling through both nostrils, filling the lungs as much as possible so that the diaphragms is lowered and the stomach extends outward like a balloon. Retain the breath for a while, then exhale through both nostrils.
  Practice this exercise for one to five minutes.
