Questions 3 and 4 refer to the following situation. Air flows into the duct of air-conditioner at 101 kPa and 12° C at a rate of 17 m³/min. The diameter of the duct is 26 cm and heat is transferred to the air in the duct by the air-conditioner at a rate of 3 W. 3. The speed (rounded to two decimal places) of the air as it enters the duct is equal to: (a) 6, 15 m/s (b) 4,87 m/s (c) 4,44 m/s (d) 5,34 m/s (e) 7,75 m/s m
