Our results show as we go deeper and do the same motions for the same time we would use more air. Knowing this information will help dive masters figure out how long people can work at a certain depth for how long with out running out of air. For example, if a dive master sends four people on a dive to weld the bottom of a bridge. Say they all had a tank 3000 psi (pounds per square inch) and the bottom of the bridge was 100 feet deep. We are trying to find a formula to show the time that they would have to make it up to the surface.
For our last trial we think it could be bad data because on the graph it passed two minutes very quickly. We have to take in consideration of being a new diver for our experiment, because when we first get in the water we usually breathe faster than normal. So for some of our first trials at more shallow depths we consume more air, then later trials at deeper depths. If I had to do my project over I would do it the old fashion way. I would decide not to use the dive computer . Overall the technology just made the project a hassle. The software for the computer was nearly impossible to decipher the information. First the pressure was in bar, and we needed it to be in psi. Next the graph was almost impossible read and take data from. Also the day before the analytical essay was due my computer broke, and before the computer broke it was very hard to transfer the information from the dive computer. So basically the new technology that was supposed to help, actually held us back. Because our results show that you use more air the deeper you go, if you are diving deep, you have to go for a shorter dive than you can at the surface. If someone is using their scuba tank at the surface, and someone else is using their scuba tank at thirty-three feet deep, then the person at the surface can scuba dive for almost double the time of the person at thirty-three feet deep. This is because at thirty-three feet deep, your scuba tank is pressurizing the air you breath to double the pressure it would be at the surface. The scuba tank pressurizes the air you breath to the same pressure on your lungs. At the surface the pressure is 14.7 in psi, at 33 feet the pressure is 29.4 If your scuba tank did not pressurize the air, you would have to take breathes twice as big as you really have to.
Due to our limit of depth, we could not perform any experiments deeper than 15 feet. If we were both certified, we could do this experiment at up to sixty feet. It would have made our results more accurate and we would be able to have better, and more numbers to work with. We also could have used more time to have more trials at each depth. Also, on the long beach dive day, Nick was sick so I couldn’t dive. It would have been much better if we could have had two different people to compare data with.
We learned that the deeper you go, the more air you breath. This was proved true by going to three different depths and doing snow angels at each depth. At the deeper depths, we used more air than at the shallower depths. When I say deeper, I mean ten and fifteen feet, and when I say shallow I mean 5 feet and at the surface. If you want to see the exact information you can look at the tables above.
