30. A classroom type room with 45students taking an exam in thermodynamics is expected to release a body heat of about 8kJ/hr per person. In order to compensate this heat dissipation, an air- conditioning unit is to be installed. If specific heat capacity and density of air is 1.0062kJ/kg-K and 1.2kg/m³, determine the volume of air flow required in examination room if the air is to be cooled down from 29°C to 20°C. a. 8.5177L¡/s b. 9.1262L¡/s c. 9.2022L¡/s d. 9.0501L¡/s
