Should I Replace The Heat Exchanger On My 1996 Furnace Or Replace It?

Posted by admin on December 9, 2009 under Heat Transfer | 5 Comments to Read


My gas company red-tagged my furnace due to carbon monoxide leaking, because of a failed heat exchanger.
Should I get the heat exchanger replaced for $1000 (parts and labor) or just get a new furnace for about $3500?
The furnace is a 1996 Tempstar 90% efficiency model.

What Chemical Engineering Elective Should I Take?

Posted by admin on November 23, 2009 under General Chemical Engineering | 4 Comments to Read


I am a junior chemical engineering student and I have one engineering elective to pick. The two choices are Unit Operations Lab II (I am already going to take Unit Ops I) or Applied Math for Chemical Engineering. I don’t have room to take both.
Which one should I pick? Why? Which is more useful?
