Air flows into the duct of air-conditioner at 101 kPa and 10° C at a rate of 17 m³/min. The diameter of the duct is 23 cm and heat is transferred to the air in the duct by the air-conditioner at a rate of 5 kW. 5. The speed (rounded to two decimal places) of the air as it enters the duct is equal to: (a) 7,36 m/s (b) 6,40 m/s (c) 4,86 m/s (d) 6,82 m/s (e) 10, 11 m/s 6. The temperature (rounded to two decimal places) of the air as it exits the duct is equal to: (a) 23, 72° C (b) 23,94° C (c) 23,65° C (d) 24,08° C (e) 24,37° C
