Outdoor pool Inground pools.
a lido is an open air swimming pool in the UK.
SchwimmbadAn open-air swimming pool is also known as a Freibad
The rays of light refract from water to the air so they refract away from the normal and this means that the bottom of the pool seems less deep than it is.
When you swim underwater at the deep end of the pool, the pressure increases on your eardrums and the air inside your ears cannot adjust quickly enough which causes discomfort or pain. This is known as ear barotrauma. To equalize the pressure, you can try holding your nose and gently blowing out, or yawning to help open up the Eustachian tube and allow air to move in or out of your ears.
At least 20 degrees lower than the air temperature.
The distance you swim in a pool is the same distance you would swim in open water. The difference is the difficulty. With open water swimming, the swimmer has to face waves, an undiverted wake, and air temperature; where as, a swimmer in a pool has lane lines to dissolve wake, a fixed temperature, and calm water.
It depends on many factors. Some of them are:how deep the pool is;how cold the pool water is;how hot the hot water is;how cold the air is;how cold the surrounding ground is;how windy it is; andhow warm you want the pool water.
It all depends on what the pool is made of for example: concrete? thickness? etc. The mass of the contents of that pool, however, can be calculated if the contents material is known: water? air? etc.
