Do we know the preconditions for the construction of ventilation ducts? If we are careful, we can find that there are many rectangular pipes on the exterior walls of some factories. From the appearance, they are made of iron sheet. Do we know what the role of this pipe is? In fact, they are used for ventilation. Because the production operations in the factory often release some gases, some are harmless gases, but some are harmful gases, so in order to ensure the health of workers in the factory, these gases need to be discharged outside. To think about this
