Do you have to be a certain weight or body type to be a scuba diver?

No, you don't need a certain body type to Scuba dive. Because you use flippers to SCUBA dive, you can be a very lousy swimmer and learn to SCUBA dive. You may look stupid with a very tight wet suit during scuba diving, but you can dive. When I got certified, I learned that you have a very slightly higher chance of the Bends during scuba diving, but this is a small percentage. The pros of scuba diving outweigh the cons.

What is the percentage of body weight to weights used in scuba diving?

What is streamlined scuba?
Streamlined scuba is just a term used for a diver who has all their gauges and equipment close to their body so they are not harming the environment around where they are diving. Commonly clips are attached to the BCD for easy access to gauges while keeping them close to your body.
What is the answer it the riddle There is a scubadiver with an empty air tank dead in the middle of the forest His body is dry and there is no water around How did he get there?
One possible answer involves a forest fire and a very charred scuba diver. During a fire a water carrying helicopter collected water from the sea in order to extinguish it. However the helicopter also picked up the scuba diver, in the sea water, and the diver was killed when he was dumped in the middle of the fire, most likely from a high altitude.
How do you calculate the concentration of a certain medicine in the body with the second grade equation but how?
Mass (weight) of medicine/Mass (weight) of body.
Do you need a mermaid tail mono fin to swim?
Monofins can have advantages in swimming efficiency for freediving. Monofins are also commonly used in underwater orienteering, a scuba based sport where fast swimming is essential. However, divers in this sport hold the scuba tank in their hands in front of them, not in a harness on their back like a recreational scuba diver. When the tank is worn on the diver's back, it interferes with the traditional monofin's function in a way that tends to negate the fin's advantages. Furthermore, a traditional monofin will induce body pitching that will sometimes result in the diver getting hit on the back of the head by the tank valve. A new type of monofin that uses a hydrofoil instead of the traditional flexible fin blade has succeeded in solving these issues and can be used with standard scuba equipment. Little to no body-pitching, and very efficient thrust production solve the monofin issues with scuba and provide advantages over bi-fins for swimming speed and reduced air consumption. See here the DOL-Fin X-15 monofin being used with scuba. See the related link for further information.
Why do divers use weight belts?
The human body is naturally positively bouyant, as is much of the gear that a diver wears. Wearing a weight belt (which is basically just a nylon belt with lead weights on it) gives a diver the necessary negative bouyancy to overcome that positive bouyancy. A diver without a weight belt would not be able to swim down more than 2-3 feet, and would constantly pop back up the surface. Some divers actually have 'weight integrated' systems, rather than using separate stand alone weight belts. But the basic concept is still the same.
If a person is scuba diving and suffers a fatal heart attack will the body float up to the surface or sink to the bottom of the ocean?
If you are scuba diving and then suffered from a heart attack, initially your body would sink to the bottom due to the diving equipment, the weighted belt, and other items. After death as your body starts to decompose it would bloat, filling up with gases, and depending upon how heavy the equipment and the weight belt that you were wearing, this would most likely cause your body to float partway to the surface, or fully to the surface depnding upon if the gases released by your decomposing body are sufficent enough to counteract the weight of any and all scuba equipment you are wearing or carrying.
Do police officers have a certain physical requirement to meet for body size and weight?
Yes there are min height weight requirements
Can a helicopter in a body in the bottom of a lake?
A helicopter can't do that, but a diver can.
What is customary dose for certain body weight called?
Usual dose is the term refers to " customary dose for body weight." so Answer to Q. : it is called "Usual dose."
How much weights a scuba diver needs to dive in the ocean?
Weight needed for scuba divingThe less overweighted you are, the more control you'll have over your buoyancy and trim. Ideally you want just enough to sink at the END of your dive - so on the surface, with a (mostly) empty tank, no air in the BCD, and no air pockets in the wetsuit you should be able and easily descend. The fine-tuning is a judgment call. Some prefer to be able to just exhale and drop and carry an extra pound or so to do so. Others feel that not carrying the extra pound is worth possibly needing to do a surface dive to get down to a level where the wetsuit compresses enough to make you neutrally buoyant. Note that if you are too light you risk not being able to do a safety stop in shallow water with an almost empty tank. A full tank can be as much as 6 lbs heavier than an empty one.Depending on the tank, the suit you wear, and your body type, weights could range from 0 to 40 lbs of lead. A medium build person with a 5-7mm suit diving an aluminum 80 cf tank may average 20-25 lbs of lead in salt water. The difference between lead needed for salt or fresh water can be almost 6 lbs.
How does scuba gear work?
Scuba stands for Self Contained Underwater Breathing Apparatus. It uses two regulators, one on the bottle which takes the volume of compressed air to a manageable rate, then the second regulator takes the air to a breathable rate so the diver can breath the air comfortable. The other part of diving is a divers buoyancy. This is controlled by using a hose which comes from the first stage regulator into a vest called a B.C. (Buoyancy Compensator). The goal of this device is to get you, the diver as close as possible to becoming neutrally buoyant (you don't go up or down, you just stay in the middle). However once neutral buoyancy is achieved it can still be affected through your breathing rate. Gregory L. Las Vegas, NV (D.I.T.)
