Slip=100%-Efficiency
Efficiency=Observed Speed or Distance / Engine Speed or Distance
Mean Apparent Slip = Distance Run by Propeller - Distance Run by Ship / Distance Run by Propeller
Distance Run by Propeller = Picth X Total Engine Revolutions per day / 1852

How does Hovercraft moves?
A giant motor connected to a propeller to push the hovercraft across the ground or water.
What is a cover slip used for?
A cover slip is a thin square of glass that you put over a specimen on a microscope slide. The cover slip stops the specimen from drying out, and squishes it so that light can get though it easier

Why does a propeller shaft have a slip joint?
Slip JointThe propeller shaft has to meet both of the changes i.e., the angular change coming between the gear box and differential and the change in length of the distance between the gear box and differential. The propeller shaft is also not on the same line as the gear box output shaft but it runs to the rear axle at an angle because the level of the rear axle is lower than the gear box.¾ To adjust 'angular motion', universal joints are provided.¾ To adjust for the change in length of the propeller shaft, a slip joint is provided.
What is slip factor?

How do you calculate resistance box for slip ring motor?
To calculate the resistance for a slip ring motor, there is an equation that must be solved. This is Torque = S/R. S is the slip of the motor and R is the resistance of the motor.
Why does my Yamaha 2 stroke outboard race when I open the throttle under load?
Provided the propeller is submerged low enough in the water, the most likely culprit would be a spun propeller hub. This condition causes the propeller to slip free from the hub, thereby causing the boat to lose propulsion.
How do you calculate propeller distance?
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.
How do you calculate propeller immersion?
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.
How do you calculate the percentage of a propellers immersion?
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)
