According to NAUI's dive tables: 25 Minutes 17 Meters for 23 minutes: Group E 30 Minutes at surface: Still Group E (Would need 55 minutes to go to D) 25 Minutes is your adjusted maximum dive time for up to 18 meters.
The final pressure group you would be in is M.
the answer is 00:28

You would be in Pressure Group F.Improved AnswerUsing which table and which depth? ... since 12 meters is not 42 feet and instead is 39.4 feet. Using PADI's RDP, you have a PG of D if using the metric table of 12 meters or the imperial table of 40 feet. If using 42 feet on the table version of the RDP, then the PG is F, but if using the wheel or the new electronic RDP, then the PG is E (as it rounds up to 45 feet).With the U.S. Navy table (or a modification thereof such as NAUI's or SSI's version), then the PG is C at 12 m./40 ft.The BS-AC' 88 table gives you a PG of C and the DCIEM table results in B.
no. oxygen and pressure is a lethal combination... 400ft has just to much pressure..you will need nitrous to dive that deep... which is very dangerous.AdditionYes, technical divers can dive to 400 feet. But they do not breathe pure oxygen (or nitrous on the bottom). They breath a combination of helium, oxygen and nitrogen known as trimix.
The no-decompression limit at 18 meters is 48 minutes and that will take you to pressure group S. This information can be found in any Table or wheel RDP (recreational diving planner) and it is basic. If you do not know how to use this table, you shouldn't really be diving. If you are in a course, then you will have a lot of time to practice. Dont forget to dive well within your no decompression limit. Live on the edge, Dive safe.
They feed at depths of around 1000 feet in the sea bed. But, they can dive atleast twice this depth. A typical dive lasts 3 to 5 mins. But, they can submerge upto 20 minutes at a time.
King Penguins are very good at swimming and diving in fact king penguins can dive up to 100 meters.They are very good at diving. Thank you for reading this please rate yes
