推证了含沙水流在水轮机中流动时，其沙子和液体的流动属于分离流动，即沙子和液体的运动速度和运动角是不相同的，且沙子质量越大，差值越大；并指出在水头相同时，水中含沙时水轮机的效率一般低于清水时的效率；进而分析了水轮机各过流部件的泥沙摩损规律。

But since there is a Limit, it is complete on every side, like the mass of a well-rounded sphere, equally balanced from its centre in every direction; for it is not bound to be at all either greater or less in this direction or that; nor is there Not-Being which could check it from reaching to the same point, nor is it possible for Being to be more in this direction, less in that, than Being, because it is an inviolate whole.

然而，由于存在空间的限制，存在在各个侧面都是完整的，就象一个很圆的球体，在各个方向上相对于中心都是对称的，因为它不可能在一个方向上小另一个方向上大；没有非存在阻止它达到同一点，存在在某一方向上多而在另一方向上少是不可能的，因为它是不可玷污的整体。
