For the natural ventilation of a single-span industrial building, when the flow coefficients of the intake and exhaust vents are equal, and the density of the air outside the building remains constant as does the density of the air being exhausted from above, which of the following statements is correct? Answer: C. When the neutralization plane moves upward, the calculated area of the exhaust window decreases. B. When the neutralization plane moves upward, the calculated area of the intake window remains unchanged. C. When the neutralization plane moves downward, the calculated area of the exhaust window decreases. D. When the neutralization plane moves downward, the calculated area of the intake window decreases
The position of the C-centering surface moves downward, resulting in a reduced calculated area for the exhaust window
The position of the C-centering surface moves downward, resulting in a reduced calculated area for the exhaust window~~~~~~~~~~~~
The position of the C-centering surface moves downward, resulting in a reduced calculated area for the exhaust window
The correct answer to this question should be C.
