NOTE: For double dilution operation, sample flow is the net difference between the flow rate through the sample filters and the secondary dilution airflow rate.

FM4 flow measurement device (Figure 15) (dilution air, full flow double dilution only) The gas meter or flow instrumentation shall be located so that the inlet gas temperature remains at 298 K (25°C) ± 5 K.

Calculation of the Mass Flow The particulate mass MPT (g/test) shall be calculated as follows: PT where: Mf = particulate mass sampled over the cycle (mg) MTOTW = total mass of diluted exhaust gas over the cycle as determined in section 2.2.1 (kg) MSAM = mass of diluted exhaust gas taken from the dilution tunnel for collecting particulates (kg) and, Mf = Mf,p + Mf,b , if weighed separately (mg) Mf,p = particulate mass collected on the primary filter (mg) Mf,b = particulate mass collected on the back-up filter (mg) If a double dilution system is used, the mass of the secondary dilution air shall be subtracted from the total mass of the do ...[+++]uble diluted exhaust gas sampled through the particulate filters.

The real challenge is double: first of all to ensure that enough equipment and broadband connections exist for pupils to be able to get real advantage from the Internet and, secondly to ensure that appropriate learning content and adapted pedagogical frameworks are set up so that the new learning paradigm (e.g. using collaborative work over the internet) can be fully exploited.
