“ Energy can neither be created or destroyed, just changed in form.”
You need to remember that whenever energy is changed from one form to another, some energy is always ______. In what two forms is energy usually wasted? 1._________ 2._________ Sound Heat wasted If you can hear a device that is not designed to make noise then energy is wasted as sound. If a device gets warm and it is not designed to get warm then energy is wasted as heat.

Heat Transfer: Questions An engineer wishes to pump hot fluid from one place to another with as little loss of heat as is possible. a) What physical characteristics  should the pipe have? (2) Narrow bore, shiny surface, low thermal conductivity, low heat capacity........
b) Should it necessarily be wide?  c) Is the rate of flow of fluid important?  No, it might increase the SA so much that more heat is lost - but that is unlikely in  most cases . Yes, the less time it is in the pipe, the less energy it is likely to lose.
Heat Transfer: Radiation Reduce surface area and used highly polished, shiny surfaces. Evaporation Reduce exposed surface area - use a lid - float polystyrene balls on surface. Methods of decreasing heat transfer - insulation (continued) Note that generally the rate of cooling increases with increased  excess temperature .
Heat Transfer: Conduction Leave a fluid (air gap) between surfaces - if the gap is “large” you might increase convection - introduce a vacuum jacket. Convection Reduce surface area and restrict the flow of the fluid - introduce a vacuum jacket.

  • 4. “ Energy can neither be created or destroyed, just changed in form.”
  • 5. You need to remember that whenever energy is changed from one form to another, some energy is always ______. In what two forms is energy usually wasted? 1._________ 2._________ Sound Heat wasted If you can hear a device that is not designed to make noise then energy is wasted as sound. If a device gets warm and it is not designed to get warm then energy is wasted as heat.

  • 9. Wasted e_____ spreads out (d_______) into the s_________. This makes the energy harder to r____. Remember energy can not be c______ or d_______. What happens to the wasted energy you get whenever energy is changed from one form to another? This is why it is important to r_____ the amount of wasted energy there is. reated estroyed nergy issipated urroundings e-use educe

  • 17. Heat Transfer: Questions An engineer wishes to pump hot fluid from one place to another with as little loss of heat as is possible. a) What physical characteristics should the pipe have? (2) Narrow bore, shiny surface, low thermal conductivity, low heat capacity........
  • 18. b) Should it necessarily be wide? c) Is the rate of flow of fluid important? No, it might increase the SA so much that more heat is lost - but that is unlikely in most cases . Yes, the less time it is in the pipe, the less energy it is likely to lose.
  • 19. Heat Transfer: Radiation Reduce surface area and used highly polished, shiny surfaces. Evaporation Reduce exposed surface area - use a lid - float polystyrene balls on surface. Methods of decreasing heat transfer - insulation (continued) Note that generally the rate of cooling increases with increased excess temperature .
  • 20. Heat Transfer: Conduction Leave a fluid (air gap) between surfaces - if the gap is “large” you might increase convection - introduce a vacuum jacket. Convection Reduce surface area and restrict the flow of the fluid - introduce a vacuum jacket.
