Ship Resistance and Propulsion : Practical Estimation of Ship Propulsive Power.
"Ship Resistance and Propulsion is dedicated to providing a comprehensive and modern scientific approach to evaluating ship resistance and propulsion. The study of the propulsive power enables the size and mass of the propulsion engines to be established and estimates made of the fuel consumpti...
