How Long Does a SCUBA Tank Last Underwater? What You Need To Know

In this video, we discuss How Long a SCUBA Tank Will Last Underwater. We go over the factors that determine how long steel and aluminum tanks last underwater. The first factor is the size of the tank, with larger tanks lasting longer than smaller ones. The second factor is the depth of the dive, as deeper dives require more gas consumption. The third factor is the diver's breathing rate, with higher rates leading to shorter tank duration. We also discuss breathing rate or respiratory minute volume (RMV) as a measure of gas consumption.

Very enlightening and informative video. If I'm allowed, I'd add a forth factor, related to the "duration" of a tank under water, the fill pressure of the cylinder. When the pressure gauge shows 220 bar, the cylinder carries more breathing mixture than when it shows 200 bar (in metric system). Keep up with the good work! Best regards!
