Fizikalne osnove potapljanja

Zupančič, Živa Hayat (author), Godec, Andrej (mentor)

Diplomsko delo govori o varnem potapljanju brez dekompresije. Na potop vplivajo številni fizikalni parametri kot so tlak okolice, parcialni tlaki plinov, globina in čas potopa ter topnost plinov. Z enačbo za tlak sem izračunala tlak okolice na globini potapljačevega potopa. Pri potopu na dah sem s pomočjo Boylovega zakona izračunala, kako se potapljačeva pljuča manjšajo z naraščajočo globino, kjer je tudi tlak večji. Vsak plin pa ima tudi svoj parcialni tlak. Ker dušik predstavlja največjo nevarnost telesu, sem izračunala parcialni tlak dušika s pomočjo Daltonovega zakona, ki na gladini znaša 0,78 bara, na globini 40 m pa 3,90 bara. Topnost dušika v krvi se z globino veča, s pomočjo Henryjevega zakona pa sem jo tudi izračunala. Da bi se izognili hujšim težavam in dekompresijski bolezni, sem na koncu še obrazložila uporabo potapljaških tablic za varen potop.

• Title: Physical principles of diving

Abstract

This work describes safe diving without decompression. There are many physical factors, such as outer pressure, partial pressure of gases, depth and time of diving, and solubility of gases. With the help of the equation to determine the amount of pressure, I calculated the pressure of diver's surroundings. When apnea diving, the shrinking of diver's lungs is based on increase of depth, which I calculated, using Boyle's law. Every gas has also it's own partial pressure. Nitrogen is one of the most harmful gas to the human body, hence why I calculated the partial pressure of nitrogen, with the help of Dalton's law. Its partial pressure on surface is 0,78 bar, whereas at the depth of 40 m totals 3,90 bar. With increasing depth, the solubility of nitrogen in blood also increases, which is determined by Henry's law. At last I explained the usage of diving tables in order to avoid serious risks and decompression sickness.
