12. 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 1.21kg/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. 8.5177Li/s b. 9.1262Li/s c. 9.2022Li/s d. 9.0501Li/s
Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
