A room measures 3.0 m by 4.5 m by 6.0 m. If the heating and air-conditioning ducts (one in and one out) to and from the room are circular with a diameter of 0.30 m, and all the air in the room is exchanged every 12 minutes: i) What is the flow rate? ii) What is the speed of the air in the ducts? a) Q = 7.6 m³/min, V = 2.5 m/s b) Q = 6.75 m³/min, V = 1.6 m/s c) Q=67.5 m³/min, V = 1.8 m/s d) Q = 6.75 cm³/min, V = 1.6 cm/s
