Finishing Chp. 17 LIQUIDS

• Forces in Fluids, and Pressure

2
What I forgot to tell you!???? Sorry

• Solids can be ductile ability be stretched into
  a wire without breaking
• GASES are considered fluids

3
Pressure of Liquids

• Pressure Force
• Area
• BEFORE
• Pressure is the same
• Inside and outside
• The straw

4

• AFTER
• Pressure outside is higher than pressure in the
  straw. The liquid moves from high to low
  pressure, this is why it goes up the straw.

5
Properties of Fluids

• Fluids always move from high pressure areas to
  low pressure areas!
• Pressure increases as you travel deeper, the
  pressure of any fluid increases with its depth.

Properties of Fluids

• Example of increasing pressure

Properties of Fluids

• Pressure of a moving stream of fluids is less
  than the pressure of the surrounding fluid.
• Bernoullis Principle speed of a fluid increases
  as the pressure decreases

Bernoullis Principle

Newton

• Force Mass X Gravity
• Force is measured in Newton(s)
• Mass is measured in Kg (grams)
• Gravity is measured in m/sec²
• 1 Newton1kgX1m/sec²
