If you have worked through Module 1 – then this one is just a little bit more challenging.
This Module looks at the Fan Laws. these are empirical, in that they are best considered ‘approximations’ to the real world but they do give you a clear picture of what will happen, for example, to the KW draw on the fan for a relatively small – say 25% increase in fan speed. And the answer is a bit of a shock!
