The curves are developed upon the theory that the water moving at high velocity has a tendency to remain in one plane, called \u00e2\u0080\u009ckinetic stability\u00e2\u0080\u009d, so that the resultant angles of reaction caused by the reversing curves of the bucket faces are not a normal result of these curves but are divergent therefrom."}, {"label": "Description", "content": "Reference:"}, {"label": "Description", "content": "This description comes from the 1939 Catalog of the Mechanical Collections of the Division of Engineering United States Museum Bulletin 173 by Frank A.
