Leftover air at 20ºC and 100kPa is driven by a fan through a horizontal galvanized conduit of 1 m in diameter and 10m in length at a speed of 10 m/s. What size motor should be used if its efficiency is 90% and that of the fan is 20%? I'm not sure where to start. My professor hasn't explained much about this subject.
