As a building services engineer, you are given a task by the management to design a new mechanical ventilation system for a new seminar room. The seminar room is designated for 60 occupants and has a dimension of 18 m x 8 m x 3.5 m. About 4 L/s of fresh air and 10 L/s of re-circulated air are supplied to the room for each person by a single-duct ventilation system. 10% of the supply volume is expected to leak out of the room. You are required to: (i) determine the room's air change rate per hour (ACH). (ii) design the suitable dimensions of the supply supply duct at velocity of 3 m/s. Given the air enter from the
