The presence of the roating propeller can be considered to have a small influence 

 on the local viscous drag on the hull surface, so that the vibrating parts of this 

 viscous drag, which are contained in the components generated by the propeller, 

 can be considered to be negligibly small compared with those caused by normal 

 pressure. Hence, the differences of the components of total force and moment 

 acting on the hull can be expressed by K^f^o? ^HFyO> etc., approximately. Next,
