Solidification Processing:
Use a lumped parameter model to estimate the temperature during cooling and so-lidification of a superheated (Ti = 700oC), spherical Al6061 droplet exposed to a room temperature (To = 25oC), turbulent flow inert gas environment (heat transfer coefficient values in the range 100 to 500 W/m2C).

Use the psychrometric chart to estimate (1) the absolute
humidity, wet bulb temperature, humid volume, dew point, and
specific enthalpy of humid air at T =30 oC and 40 % relative
humidity, and (2) the amount of water in 150 m3 or air at these
conditions. Students must sketch the psychrometric chart and draw
the path of determining the parameters of (1).

David McLemore, the CFO of Ultra Bread, has decided to use an
APT model to estimate the required return on the company's stock.
The risk factors he plans to use are the risk premium on the stock
market, the inflation rate, and the price of wheat. Because wheat
is one of the biggest costs Ultra Bread faces, he feels this is a
significant risk factor for Ultra Bread. How would you evaluate his
choice of risk factors? Are there other...
