Q4. (a) Figure Q4-1 illustrates the arrangement of openings for a naturally ventilated building. The design outdoor temperature is 23°C, design indoor temperature is 26°C. With the information given in the Figure and appropriate assumptions, determine: (i) the location of neutral plane measured vertically from G/F; the air flow rates at openings a, b1 and b6. (ii) Assume the air density is 1.2 kg m³, wind speed = Oms, flow coefficient of openings C=0.65.
