Why should scuba divers be able to dive near coral reefs?
So that the divers are able to take pictures, provide research, and monitor the sea life and the changing temperature
Are scuba divers fat?
Generally no. They need to be quite fit to be able to swim in the water :)
How often should you equalize your air spaces when SCUBA diving?
Early and often. Divers should equalize immediately after breaking the surface, and frequently while descending. If you let the pressure build up too much, you may not be able to clear until you ascend.
I would really like to scuba dive so im wandering what in the way of physical exercise should i be able to do. I know that I need to be able to swim 200m and walk a mile in 12 mins but what else?
You don't. People use their air faster if they over exert themselves, so divers learn not to. The level of fitness required to swim 200m is all you need. Its good practice to do press ups, squats etc, but that's to be a better scuba diver, not to be one at all.
Who started scuba diving?
The History of Scuba diving goes back through the centuries People have been diving underwater throughout the ages, probably for as long as people have been swimming….. It may not have been Scuba but it is the beginnings of the quest throughout the history of scuba diving to be able to dive underwater and be able to breath underwater. There are records, in some cases little more than myth, of the methods used and what was done while diving. Read more at this site:
Why is lead used as a scuba diving belt?
We all float. Wearing a neoprene (rubber full of bubbles) wetsuit makes SCUBA divers really floaty!!!! SCUBA divers wear lead belts to counteract bouyant force (see below). If they didn't wear lead belts they would never be able to get and stay underwater. SCUBA divers have to learn the specific amount of lead weight they need to carry. Their are numerous factors that affect SCUBA divers including type of wetsuit worn (a 7mm wetsuit is a lot more floaty than a 3mm wetsuit), body mass, equipment configuration, etc. Most usually start at about 10% of their body weight but with practice, they are able to drop this to 5% and even less. From Wikipedia, the free encyclopedia The forces at work in buoyancy In physics, buoyancy (BrE IPA: /ˈbɔɪənsi/) is the upward force that keeps things afloat. The net upward buoyancy force is equal to the magnitude of the weight of fluid displaced by the body. This force enables the object to float or at least seem lighter.
Would a person be able to scuba dive after having Ileoanal Anastomosis surgery?
It is not advisable to scuba dive after having lleoanal Anastomosis surgery. Any type of outdoor activity should be cleared with a medical professional after a medical procedure is performed.
What is an example sentence for scuba?
Remember SCUBA stands for Self Contained Underwater Breathing Apparatus So a sentence would be: For a scuba lesson i`m the fastest and flex able so i won.
Why do people scuba dive?
People scuba dive because it enables them to stay underwater much longer than they would be able to do so without breathing apparatus. SCUBA stands for self contained underwater breathing apparatus. It is different from surface feed or Hooka diving where air is pumped down because it gives you more freedom. People have been able to hold their breath for up to 8 minutes but when you move about you can only hold your breath a short time. Taking an air supply means you can spend a long time underwater without being restricted by an air pipe from the surface.
Why when scuba diving why do they equalise their ears and how do they do it?
There are several, already answered questions on this subject. Scuba-divers have to equilize their ears during decent, because the middle ear doesnt automatically pressurize (unlike other body parts, like sinuses). This is done by covering/squeezing ones nose using the thumb and index finger, and gently blowing air out your nose. The air, not being able to escape through the nose, will be redirected to the middle ear, thereby pressurizing it.
What legal requirements do you need to scuba dive?
There are no legal requirements to scuba dive. In other words, anyone can scuba dive without breaking a law (assuming you are not doing an illegal underwater activity such as illegal fishing). However, if you are not certified, you will not be able to rent or buy equipment or get someone to fill your scuba cylinder.
Scuba diving and math?
Many ways:1) The volume of air stored in a tank2) SAC or also known as the rate at which we breath, and what that translates to in terms of "how long can I dive with this size tank"3) The conversion of units and the differences in US and metric systems. see:How_many_cubic_feet_in_a_12_liter_cylinder
