A building requires a volume of 3 m³s^–1
of fresh air. The air is supplied from a conditioning plant a distance of 120 m away for which the permissible pressure drop along the supply duct is 5 kNm^–2. Determine the required pipe diameter if the variation of friction factor is

The air has a density of 1.2 kgm–3 and viscosity of 1.7 × 10^–5
Nsm^–2.
