 39, pp. 251-259. The author finds an augmentation 

 of polar moment of inertia of 60 per cent of the 

 corresponding polar moment of mass of a steel 

 screw propeller. He mentions the fact that an 

 augmentation percentage of 25 is generally used, 

 as listed in Sec. 62.6 of the present book.
