查询词典 loss system

Used the finite element method computation pipe network resistance thus obtains the ballast water system the line pressure distributed situation. The paper also has carried on the computation to the ballast tank hydraulic loss and has provided the theory basis to the ballast pump optimized design. The overpressure to the ballast tank has been carried on the discussion. The paper also gets the function between the rated flow and the rated pressure of the pump on ships whose BW pipe net is uniform and line is different, which provides a new method for the selection of BW pump.
