密闭容器内加热水(水不充满)到一定压力,请产生的蒸汽量
Reply #42019-06-01
举个实际的例子吧:直径3.5米而高度6米的密闭罐体,盛水高度为6米。初始水温20℃,罐体内常压。加热把罐体内水加热到110℃。请问到个温度时罐体内产生了多少的水蒸气? (这是一个变压加热过程)

这是要考数学吗?个温度对应压力个MPa个饱和蒸汽密度个0.1

用下面的办法计算个不知是否可行? P*V个=n*R*T ; ρ (V个-V个)+个8=n(个*(个)个V (个)P——个水在个温度的饱和蒸汽压;V个个 (个)个水蒸汽的体积(未知);n个——个水蒸汽的量(未知)。 ϴ个个个水在个温度的饱和蒸汽密度;V个个罐的容积;( ϴ个个 (个)个水在个温度的饱和蒸汽密度;V (个)个 (个)个水蒸汽的体积。

谢谢!我觉应该按这个计算的个还有一点疑问请教个初始个2℃时上上空间是有充满空气然后常压的不知道影响计算不?
