Vacuum degree and saturated vapor pressure
Thread Content
Hello, esteemed seniors! If the user uses water for this purpose, he told me that the water temperature is 80°C, and at this temperature the saturated vapor pressure of water is 47 Kpa. To bring water to a boil and cause it to evaporate, the vacuum level must reach 0.053 Mpa. Considering the water-soluble substances produced by the materials. So the vacuum level needs to be increased further. Is this understanding reasonable? Question 1: Is this understanding reasonable? Question 2: Is the key point the vapor pressure of the user’s water-soluble solutes? Question 3: If 1 is not reasonable, from the user’s perspective, how should the vacuum level be considered? I’m a “primary school student”; I’m not sure if this discussion is very meaningful. Please, seniors, give me some advice
As long as the vacuum level in the upper water space is maintained at 53 Kpa, the water at 80°C in the liquid phase will continue to evaporate, and the steam generated must be continuously removed.
