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

The paper is 1.0 mm thick and the tube has an outer diameter of 100 mm. Determine the shear stress acting along the seam, which is at 50° from the horizontal, when the tube is subjected to an axial compressive force of 200 N. Express your answer to three significant figures and include appropriate units.
