热水喷泉现象的理论研究

摘要

研究了莫尔吸量管中吸入部分热水产生的喷泉现象，应用伯努力方程得到最大喷射高度的表达式，讨论了吸水高度、平衡温度及喷嘴孔径对最大喷射高度的影响。通过多项式拟合求得平衡温度与吸水高度的关系式，解决了平衡温度不易测量的难题。%The fountain phenomena were studied when a Mohr pipette was partially filled with hot water .The formula of the maximum jetting height was deduced using Bernoulli equation ,and the in‐fluences of suction height ,equilibrium temperature and nozzle aperture on maximum jetting height were discussed .The relation between temperature and suction height was obtained by polynomial fit‐ting ,thus the equilibrium temperature was measured easily and accurately .
