Transcript Chapter 10 Fluids

Chapter 10
Fluids
•4 phases of matter
solid, liquid, gas, plasma.
•Liquids and gases will
collectively be referred
to as fluids.
10-1 Density
• We will use the symbol r for
density
• r= m/v
• See example 10-1 p276
• See density chart p 276
10-2 Pressure in Fluids
• Pressure=P=F/A
• P= F/A=mgh/A
• P=F/A=rAgh/A so
P=rgh
• See Example 10-2 p278
10-3 Atomospheric Pressure
•
•
•
•
1 atm= 1.013 x105 N/m2 = 1.013 x105 pa
The SI unit for pressure is the Pascal
1 bar = 100 kPa
Guage pressure is pressure measured at a
local guage.
• To get absolute pressure, one must add the
atomospheric pressure, Pa , to gauge pressure.
