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 recreational dive limits for this dive site are typically a maximum depth of 60 feet and a maximum dive time of 60 minutes.
To calculate the maximum allowable time for the second dive to 50 feet after a 30-minute surface interval, you need to consult a dive table or computer. Generally, a dive to 50 feet allows for a maximum time that typically ranges from 60-90 minutes, depending on the dive table used and the depth of the first dive. Given the first dive was to 59 feet for 22 minutes, and considering no residual nitrogen buildup, a safe estimate for the second dive would likely be around 60-70 minutes. Always refer to the specific dive table or computer being used for accurate limits.
An interval is the spacing of time. For example: I ran for an interval of 10 minutes then walked for an interval of 30 minutes. Or each car has an interval of 0.5 seconds.

I went out for interval for 10 minutes.
If your first dive is to 60 feet for 50 minutes, you should refer to a dive table or computer for no-decompression limits, which typically allows for a maximum dive time of around 55 minutes at that depth. After spending one hour and 40 minutes on the surface, you have effectively re-gained some of your allowable dive time, but the exact adjusted maximum dive time would depend on the specific dive table or computer used. Generally, after such a surface interval, you may gain back around 10-15 minutes of dive time, but it's crucial to consult your dive plan for accurate limits. Always prioritize safety and adhere to the guidelines provided by your dive training agency.
lunitidal interval hrs of Singapre is 10:20
Whatever 'b' is count the number of 'b' in any time interval. 5 minutes for example. then divide by the number of minutes in the time interval.
If suppose a tea break is given in a discussion session, say for 15 minutes, then this duration 15 minutes is the length of the interval. If we have to increase that length then we may make it to be 20 minutes.
