A flow-through electric water heater has a 22 kW electric heater inside an insulated 2.0-cm-diameter pipe so that water flowing through the pipe will have good thermal contact with the heater. Assume that all the heat energy is transferred to the water. Suppose the inlet water temperature is 12° C and the flow rate is 8.0 L/min (about that of a standard shower head).

Hello! I'd like help with the following exercise, from Levenspiel's "Engineering Flow and Heat Exchange". 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.
