Ans. The pressure group (pg) at the end of the dive will be K.
Since, I dive to a depth of 11 metres/39 feet and stays for 46 minutes, then the pressure group (pg) at the end of the dive can be find out using Recreational-Dive Planner which is designed specifically for recreational dives i.e. on air only and no decompression dives. With the help of Table 1 of Recreational –dive Planner, the pressure group (pg) can be find out which is K group for 11 metres/39 feet and time 46 minutes.
