Variations+in+Fluid+Pressure



Have you ever felt fluid pressure? You probably have with the every day things you do. Driving down a hill, flying in a plane, swimming in the deep end of a pool. Changing your elevation changes the pressure were you are. When your ears pop that the pressure changes. Fluid pressure depends on depth. At just 10m below sea level the pressure doubles. As elevation increases atmospheric decreases. Water pressure increases as depth increases. At sea level atmospheric pressure is about 100,000 N/m2 (Jones).

BY MICHAEL and EMILY

Atmospheric Pressure decreases gradually as the elevation aboce Sea level increases. Water pressure increases rapidly as water depth increases. PLANE- Air planes usually fly at 12,000 m. THe Atmospheric pressure is 20% at sea level(Jones).

HELOCOPTER - Some helocopters reach 6,000 m above sea level. The atmosphere there is about half that at sea level (Jones).

SKYDIVER- Skydivers jump from about 3,000m. Air pressure is 70% that at sea level (Jones).

BOAT- At seal level. standard atmospheric pressure is about 100,000 N/m (Jones)

SCUBADIVER- Only 10 m below the surface. the pressure on the diver is double the pressure at sea level (Jones).

FISH- The gulper eel can survive at 2,500 below surface. Pressure here is about 250 great here than at sea level (Jones).

SUBMARINE- A submarine can explore as deep as 6,500 m. Here water pressure is 650 times greater than at sea level (Jones).
