1 .问 :用一只容积为 4 0升、 150型钢瓶灌装二氧化碳 2 4ｋｇ ,请问在液体全部汽化、瓶温 60℃下 ,瓶内压力为多少 ?是否安全可靠 ?答 :为计算ＣＯ2 全部汽化 ,温度为 60℃下钢瓶内的压力 ,可按三个步骤进行 :( 1)将液体ＣＯ2 的状态先查出充装时温度为+5℃时的饱和蒸汽压Ｐ1=
Q: With a volume of 40 liters, 150 cylinders filled with carbon dioxide 24kg, what is the pressure in the bottle when the liquid is completely vaporized, the bottle temperature is 60 ℃? Is it safe and reliable? A: In order to calculate all CO2 Vaporization, the temperature of the cylinder pressure at 60 ℃, can be carried out in three steps: (1) the state of the liquid CO2 first check filling temperature +5 ℃ saturated vapor pressure P1 =
