About our syringes and oil ...

What do we have to assume about the pipe?

• It affects flow

• Attachment is non-laminar

• It is a constant

• Bendy is better

About our syringes and oil ...

IF the small syringe is 3ml and the large syringe is 30ml, what is the ratio?

• 15:1

• 20:1

• 100:1

• 10:1

About our syringes and oil ...

FORCE = ?

• Pressure (P)
  X
  Volume (v1)

• Pressure (P)
  X
  Volume (v2)

• Pressure (P)
  X
  Area (a)

• Pressure (P)
  X
  Mass (m)

A bit of Bernoulli...

What is the relationship between v1 and v2?

• v2 is greater than v1

• v2 is less than v1

• v1 and v2 are the same

• There is no relationship between v1 and v2

What is 'v'?

• Volume

• Venom

• Vortices

• Velocity

What is 'dv'?

• Volume

• Venom

• Vortices

• Velocity

What has happened (in this example) to A2 versus A1?

• Area has increased

• Area has decreased

• Area has remained constant

• Area has erased

In the diagram, what is the relationship between v1 and v2?

• v1=v2

• v1<v2

• v1>v2

• v1-v2=v3

At the constriction (area a2) what happens to pressure?

• Pressure increases

• Pressure balances

• Pressure expands

• Pressure decreases

Hydraulically, what do these symbols represent?

• Motors

• Accumulators

• Capacitors

• Pumps
