What is the absolute pressure at 17 fsw?
The determine the pressure at 17 feet under sea water (FSW) you need to calculate the pressure at sea level which is 14.7psi. Then add .0447 per foot under sea level. S0 14.7psi added to 17*(.0445). it would equal 22.265 psi or the absolute pressure.
What is the oxygen percentage at sea level?
the aircontains 20.93% oxygen-whether you are swimming in the Dead Sea in Israel (1,369 feet or 417 meters below sea level) or standing on top of Mount Everest in Nepal (29,035 feet or 8,850 meters above sea level). the barometric pressure is lower the higher in altitude you go so the pressure of oxygen is lower therefore its harder for your lungs to absorb the oxygen.
How long does it takes a sound to travel a distance of 1900 feet?
In dry air at sea level and atmospheric pressure, 1.69 seconds.
How much pressure would there be if you go 4 miles under the sea?
About 4 tons per square inch
What means psig?
In standard English: "What does psig mean?" The abbreviation stands for pounds per square inch gauge. PSI is a standard unit of pressure, which may be converted to/from Pascals. "Gauge" here means relative to surrounding atmospheric pressure. So a reading of 100 psig means a pressure of 100 psi *above* the atmospheric pressure, which is around around 14.7 psi at sea level, making 114.7 psi absolute pressure.
