9、公斤的壓力，絕對大氣壓=表壓+1),184度是11公斤絕對大氣壓下的飽和蒸汽對應(yīng)溫度。這里都強調(diào)“飽和蒸汽”，因為還有“過熱蒸汽”，過熱蒸汽的溫度是不于壓力成對應(yīng)關(guān)系的。Antoine公式: ln(P)=9.3876-3826.36/(T-45.47)【T在290500K之間】 P：MPa T：K 我用這個公式算出來是T=452.77K 約179度.不知道對不對?請高手指教!飽和蒸汽壓力、溫度對照表制硝 2008-05-24 10:53:57 閱讀16207 評論10   字號：大中小 訂閱 壓力MPa溫度壓力MPa溫度壓力MPa溫度壓力MPa溫度0.00099.
