    The relationship between fluid pressure and flow velocity: the greater the flow velocity, the smaller the pressure, it can be seen that when the range hood is working, due to the large flow velocity and small pressure of the gas at the rotating fan blade, the oil smoke is pressed to the fan mouth under the action of the surrounding atmospheric pressure

    When the range hood is working, due to the large flow rate and low pressure of the gas at the rotating fan blade, the oil smoke is pressed to the fan mouth and discharged under the action of the surrounding atmospheric pressure; In the Qinghai-Tibet Plateau in China, due to the decrease in air pressure, the boiling point of water decreases, and people sometimes have to use pressure cookers for cooking

    So the answer is: small; Barometric pressure

    The flow rate of the gas at the fan blades of the shouting and reeds is large and the pressure is small, so that the oil smoke is pressed to the mouth of the fan Zheng belt under the action of the surrounding atmospheric pressure

    So the answer is: small;
