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

weight of fluid= ---------------- area

mg= ----- area

density volume g= ------------------------- area

density (area height) g= -------------------------------- area

pressure = density height g

P = ρhg gauge pressure

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
