# How do you calculate propeller slip?

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

I wish this can help those who are in need of this formula.

### Why does a propeller shaft have a slip joint?

Slip Joint
The 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.

### How propeller slip is calculated in a ship?

The propeller slip on a ship is calculated by comparing the
distance the ship travels say in 24 hours with the theoretical
distance the propeller should have travelled according to its
pitch.
If the ships propeller has a pitch of 5 metres then it is trying to
advance through the water at a rate of 5 metres / revolution. If
the engine is turning at 100 RPM then this is 500 metres / minute
or 720000 /day IE 720 kilometres.
If the mate calculates the ship actually travelled 700 kilometers
then the apparent slip is
difference between engine miles and true miles / engine miles *
100
IE 2.7%

### How do you calculate the percentage of a propeller's 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 blade
Dp : Propeller Diameter
xtip :x Position of propeller tip from A.P (in m)
Lpp : Length Between perpendicular of the ship.
