1. Two mine airways with resistances of 0.5 Ns2/m8 and 1.2 Ns2/m8 are connected in series determine the resistance of the series combination. If the airflow through these airways is 27 m3/s, what is the pressure drop in each of the airways and the total pressure drop in the series combination of airways?

2. Three mine airways with resistances of 0.5 Ns2/m8, 0.4 Ns2/m8 and 1.2 Ns2/m8 are connected in series determine the resistance of the series combination. If the airflow through these airways is 27 m3/s, what is the pressure drop in each of the airways and the total pressure drop in the series combination of airways?

3. Two mine airways with resistances of 17 and 11 Ns2/m8 are connected together in parallel. Determine the resistance of the parallel combination. If 35 m3/s flows into this parallel combination of airways determine the flow in each airway.

4. Two mine airways with resistances of 1.5 Ns2/m8 and 1.2 Ns2/m8 are connected in series determine the resistance of the series combination. If the airflow through these airways is 54 m3/s, what is the pressure drop in each of the airways and the total pressure drop in the series combination of airways?

5. A section of a mine ventilation system is connected together as shown in the diagram below, if the pressure drop across the system is 1.1 kPa and the resistances are as indicated determine the flow in each airway.
