Purpose of Course showclose
- Read this recent report by Gary Goettling for the Georgia Tech Alumni Association.* In it, Goettling describes a refrigeration system with no moving parts based on improvements to a patent filed by Einstein and Szilard in 1930. As an engineer, how would you go about evaluating this design for energy efficiency, safety, reliability, and manufacturing, operating, and installation costs?
- Have you ever wondered how the level sensor on a retail gasoline dispenser automatically shuts off when the gasoline tank in an automobile is full?
- Have you ever been tempted to share your opinion concerning the debates about global climate change? Global climate involves consideration of radiation, convection, and chemical change amongst many other factors.
- Have you wondered how it is possible to estimate the composition and flow rate of a mixture of petroleum, water, and natural gas at a remote location five miles under the ocean surface.
- Just how dirty do your air filters need to be in your domestic air handling system or on your motor vehicle for it to be economically advantageous to replace them?

Unit 2: Measurement of Flow
In order to assess pumping and piping operations, you must know the mass and volumetric flow rates and velocities in the system, which you can infer from the pressure differences and resulting actions upon various sensors. Some of these methods may seem as crude as watching a weather vane or the motion of a flag in the wind, but they can be essential for monitoring equipment and process performance.

Unit 4: Piping Networks
Piping networks are useful for moving fluids from points of generation or storage to points of use or disposal. Think for a moment about the many piping systems in an automobile: fuel lines from the storage tank to each cylinder of the engine; exhaust lines from the cylinders to the tailpipe; coolant lines from the engine block to the radiator; and conduits for ventilation and temperature regulation of the passenger compartment, amongst many others. You will learn in this unit how to approach problems associated with materials compatibility, pressure losses, and vibration and anchoring in fluid piping systems.

Unit 5: Heat Exchangers
Heat exchangers are commonplace in a wide variety of situations that you encounter on a daily basis. They involve the transfer of heat energy from one fluid to another through physical proximity and involve simultaneous conductive and convective heat transfer. Some common examples include the radiators (a bit of a misnomer) used to remove heat from automobile engines, the coils used to transfer heat from the inside of a refrigerator to the outside, the large ears of some mammals (which can aid in cooling), and the fins on a computer chip. In this unit, you will learn about the importance of fluid mechanics, exchanger geometry, and flow configuration in heat exchanger efficiency.

Unit 6: Cooling and Refrigeration
You may be familiar with different types of cooling equipment and operations. All of these involve the transfer of energy from a high temperature source to a low temperature sink. The cooling of your body by a combination of convective heat transfer and evaporation of sweat is an example with which you are certainly familiar. It has much in common with the operation of the cooling towers you may associate with large power plants. Another familiar example involves the absorption of heat at low temperature by the expansion of a gas and the rejection of that heat at a higher temperature by the compression of a gas. This type of operation can be found in a home air conditioner or refrigerator.
