EXOTIC BEACH GILI AIR LOMBOK INDONESIA
General Information
Gili Air is the nearest Gili to Lombok. It is also the most populated and you will find more trees there than the other Gili's. The local inhabitants are: Sasak, Mandar, Bugis and Makassar. You can find their unique culture that is different from Lombok and wonderful beaches. Many of the older generation still make their living as boatmen, fisherman and farming coconuts.
There are only a few number of 2 stars hotels (rooms with air conditioning, swimming pool, TV etc) on Gili Air. Most of places to stay are located in south, west and east side of the island. You can find many homestays or budget accommodation on this island. The island remains quiet and relaxing.
Most accommodations are locally owned and managed, while a few of the upmarket hotels own and managed by foreign investors. You can go from one island to another by joining the gili island's hoping boat (depart twice a day). People here are more friendly than on Gili Trawangan.
Activities
Snorkeling and diving are the highlight of the activities. Snorkeling area are located in the south east (opposite-facing the Lombok Golf Kosaido) and along to the north east). You can just jump into the water to see the colorful fishes and coral reef. In the western part of Gili Air you can't snorkel off the beaches. When the moon is high (low tide), you can't swim off the beach. You need to walk to the south or east side.
There are few quality scuba diving operations on all the islands.
While the island is busiest from May through August, the quieter off-season from January to April provides a better opportunity to enjoy all the islet has to offer, with accommodation prices at their lowest level.
To get around the isle, the only means of transport are Cidomos, horse drawn carriages. Bicycle rentals are available too. Expect higher prices for most things there since all food and goods must be brought over from the mainland.

Atmospheric And Hydrostatic Gas Presure
Atmospheric Pressure is produced by the weight of the gases in the atmosphere, acts on every body and in all directions. Its effects are therefore neutralized. At sea level, it equals 14.7 psi or 1.03 kg/cm2; larger values are often expressed in atmospheres. Atmospheric pressure decreases with the increase of height.
Hydrostatic Pressure is produced by the weight of a fluid, acts upon every body in the fluid, and is one and the same in all directions at a particular depth. Its increase rate is .445 psi/foot (1 kg/cm2 per 9.75 meters) when descending in seawter, whereas in fresh water it increases at .432 psi/foot (1 kg/cm2 per 10 meters).
Absolute Pressure = Atmospheric Pressure + Hydrostatic Pressure Its units of measurement are pounds per square inch absolute (psia) or kilograms per square centimeter absolute (kg/cm2 absolute).
Gauge Pressure is the difference between the absolute pressure and a specific pressure. It is measured with gauges that read zero at sea level. To convert to absolute pressure add 14.7 to the value in psi or 1.03 to the value in kg/cm2.
Partial Pressure is the fraction of the total pressure contributed by a gas in a mixture. It is in direct proportion to the volume percentage of the gas in the mixture.
The Buoyant Force is a very characteristic force that acts upon all submerged bodies. This is how Archimedes' Principle explains buoyancy:
A body immersed in a liquid, either wholly or partially, is buoyed up by a force equal to the weight of the liquid displaced by the body.
The following mathematical equation can be derived from Archimedes' Principle: the buoyancy of a submerged body = weight of displaced liquid – weight of the body. Therefore, we may conclude that:
1 The body will float if the buoyancy is positive (body weight < weight =" weight"> weight of displaced liquid).
The buoyant force of a liquid depends on its density, which equals its weight per unit volume.
The density of fresh water is 62.4 pounds per cubic foot (28.3 kg/ 0.03 m3).
Seawater, however, is denser: 64 pounds per cubic foot (29 kg/0.03 m3). A body immersed in seawater will, therefore, be buoyed up by a greater force than a body immersed in fresh water, so it is easier to float in seawater than in fresh water.
Lung capacity affects the buoyancy of a person. A diver with full lungs displaces a greater volume of water and, according to Archimedes' Principle, is more buoyant than a diver with deflated lungs. With full lungs, a diver’s relative weight is .96-.99; with deflated lungs: 1.021-1.097. Bone structure, bone weight and body fat are other factors that have an effect on buoyancy and vary from person to person. That is why some people float more easily than others.
Divers who wear wet suits often add diving weights to their weight belts to create the negative buoyancy needed for descent. At the desired depth, they adjust their buoyancy to an appropriate level so that work can be accomplished without extra physical efforts to oppose positive or negative buoyancy.
Usually, a person’s weight is slightly less than the weight of the displaced amount of water. For example, a person who weighs 80kg displaces 79dm2 of water, which weighs 79kg, that is, he has about 1kg of negative buoyancy. Balance under water depends on the location of the center of weight and that of buoyancy. If they are situated on a vertical line (the symmetry axis of the human body) and the center of buoyancy is higher than that of weight, equilibrium will be stable.
The relative weight of seawater is considered 1. That is why the loss of weight of submerged bodies in Newtons corresponds to the displaced volume in liters. The human body has a relative weight of about 1, which is why it weighs little under water . To ensure normal descent, it is not enough to regulate the weight of the diver. It is also necessary that the additional weights attached to the weight belt be situated so as to provide stable equilibrium, on condition that the equipment is intact.
All weight forces can be added and presented as a single force applied to the center of weight. Similarly, buoyant forces correspond to the center of buoyancy, located just above the center of weight. The distance between the two centers must be about 20cm. This fact allows the diver to maintain the erect position of his or her body.
If the belt weights are situated too high and the center of weight turns out to be above that of buoyancy, the diver will be rotated upside-down.
If the belt weights are situated too low, the center of weight would be much lower than that of buoyancy. As a result, the diver will be unable to bend or accomplish underwater work.
