Propeller immersion is calculated by determining the vertical distance from the waterline to the center of the propeller hub. This is done by measuring the waterline depth and subtracting the hub depth from it. The resulting value indicates how deeply the propeller is submerged, which is crucial for ensuring optimal performance and efficiency in marine vessels. Proper immersion helps prevent cavitation and ensures effective thrust generation.
Propeller immersion refers to the depth at which a boat's propeller sits underwater. The immersion level affects the performance and efficiency of the propeller in moving the boat through the water. It is important to adjust the propeller immersion to optimize the boat's speed and fuel consumption.
Propeller Immersion : (dA - (xtip X Trim)/Lpp - H) / Dpx100 (in %)Where dA : Draught at A.P (in m)H : Height of lowest tip of propeller bladeDp : Propeller Diameterxtip :x Position of propeller tip from A.P (in m)Lpp : Length Between perpendicular of the ship.================Mosfofa Sowkot ImranNaval ArchitectBangladesh University of Engineering & Technology (BUET)

To calculate propeller distance, you typically need to know the diameter of the propeller and the number of revolutions per minute (RPM). The distance covered per revolution can be approximated by the propeller's pitch, which is the distance the propeller would move forward in one complete turn. The formula is: Distance = Pitch × RPM × Time (in hours), giving you the total distance traveled over a specified time period. Adjustments may also be needed for factors like water resistance and efficiency.
