2
General Energy Equation
No consider the effects of heat transferred into
or out of the fluid at this time.
3

• hA Energy added (Major Losses)
• hR Energy removed
• hL Energy losses (Minor Losses)
  Friction

Darcys Equation
Laminar Turbulent Flow
hL energy loss due to the friction (N.m/N, m,
ft-lb/lb, or ft) L length of flow stream (m
or ft) D pipe diameter (m or ft) v
average velocity of flow (m/s or ft/s) f
friction factor (dimension less)
5
Laminar and Turbulent Flow

• Water faucet slowly
• Smooth and steady

• No longer smooth and regular
• Chaotic manner

6
Predicting the Type of Flow

• It depends on

Osborne Reynolds is demonstrated for the laminar
or turbulent flow.
Laminar
Critical Region
Turbulent
7
Viscosity Measurement

• Rotating drum viscometer
• Falling ball viscometer
• Saybolt universal viscometer

8
Conclusion

• General energy equation and Darcys equation are
  used instead of Bernoulli equation because of
  some energy losses and additions between the two
  sections of interest.
• The energy loss due to friction in the flowing
  fluid is due to its viscosity.
