At 4 meters below the sea level, the pressure exerted by the water column above the diver would be approximately 0.4 atmospheres higher than atmospheric pressure at the surface. Therefore, the expected pressure of air in the diver's lungs would be the sum of this increase and atmospheric pressure.
The pressure at 18 feet below the surface of water can be calculated using the formula P = ρgh, where P is the pressure, ρ is the density of water (1000 kg/m^3), g is the acceleration due to gravity (9.81 m/s^2), and h is the depth (18 ft converted to meters). Plugging in these values, the pressure at 18 feet below the surface of water is approximately 6.8 psi.
At 18,000 feet above sea level, the atmospheric pressure is approximately 50% of what it is at sea level. This is because air density decreases with altitude, resulting in lower pressure levels.
The atmospheric pressure at sea level is typically around 760 mmHg. As you increase in altitude above sea level, the atmospheric pressure decreases. For example, at 5,000 feet above sea level, the atmospheric pressure may be around 625 mmHg.
Being 100 feet below sea level means you are situated underwater, in a submerged location. Being 100 feet above sea level means you are located higher in altitude, above the water level.
15.78 psi
The speed of sound in water is affected by temperature, salinity, pressure, and depth. Typically, the speed of sound increases with depth due to increased pressure, so it is likely louder at 300 feet below sea level compared to 200 feet.
40 feet below sea level is at a higher elevation than 14 feet below sea level. Elevation is measured by the distance above or below a reference point, such as sea level, so the higher the number below sea level, the lower the elevation.
About nine feet below sea level.
5 feet below sea level is higher. Because if you have 5 feet below sea level then you go from the average height if the top of the water and go 5 feet under it, and if you have 4 feet below sea level then you go from the average height if the top of the water and go 4 feet below, so 4 feet is higher.
40 feet below sea level.
The lowest point on the earth surface is 1200 feet below sea level . It is located in the Dead Sea in the present nation of Israel.
it is 12,600 feet below sea level.
Standard atmospheric pressure at sea level is about 14.7 PSI. So, then what is the pressure at about 5,645 feet below the surface of the earth?
If sea level is 0, then feet above sea level would be a positive integer, while feet below sea level would be a negative integer. The integer for six feet below sea level would be -6.
3 miles below sea level is approximately 15,840 feet below the surface of the ocean. At that depth, the water pressure would be extremely high and the environment would be completely dark.
