Advice(s) :

The training difficulty of this lesson is NVQ Level (Vocational Certificate) to HND Level (Associate’s Degree).
The first four § of this E-book are essential for working in the HVAC sector. At the Certificate and A level the book should be read entirely, but we will only deal with the exercises of the first four §.
Before studying this chapter download and print the PDF exercise. Write down your answers to the exercise before checking the corrections on-line.


Training lesson requirement(s) :

Studying the last paragraph demands detailed knowledge of the E-book “Volume & mass flow rates in HVAC”. If you do not master this, leave this § till later.
