Another chapter is at its end: you have finished chapter 5.1. Great job!

In this chapter, you have applied Newton’s law of cooling to a double glazed window and solved a complex problem about the pasteurization of milk. The geometries involved, however, were still rather simple. For more complex geometries, it can be rather difficult to derive the heat transfer coefficient, because the Nusselt number is hard to determine. The DIY of this week deals with an experiment which can easily be performed at home, yet shows a nice application of Newton’s Law of cooling in a more complex situation.

Before we arrive at the DIY, though, there is one more subsection to go. In this subsection, you will really come to appreciate the analogies between heat and mass transfer.

Good luck!
