PRESSURE OF A FLUIDPRESSURE OF A FLUID
Barometer
air pressure pressure = height of mercury column
Gauge pressure ndash pressure above the atmospheric pressure
absolute (total) pressure =gauge pressure + atmospheric press
Pressure is produced by the weight of the fluid above the surface
forcepressure = ------ area

pressure Nm2 = Pascals (Pa)
density kgm3
height (depth) m
P = ρhg + P0 absolute pressure
Standard atmospheric pressure
760 mm Hg asymp 30 in Hg
Calculate 1 atm in Pascals
P = ρgh
ρHg = 136 x 103 kgm3
g = 98 Nkg h = 0760 mP = 1013 x 105 Pa
Pressure of fluid depends on depth
ldquoWater seeks its own levelrdquo
Pressure does not depend on volumeonly on height (depth)
More pressure at greater depth
