The formula to calculate the Propeller Slip is:
\[ \text{Slip} = \left(\frac{N - S}{N}\right) \times 100 \]
Where:
Propeller slip refers to the difference between the theoretical distance a propeller should move in one revolution and the actual distance it does move. This discrepancy is due to the fact that water or air is a fluid medium, and when a propeller rotates, it pushes against this medium to generate thrust.
Let's assume the following values for an example:
Using the formula:
\[ \text{Slip} = \left(\frac{1000 - 900}{1000}\right) \times 100 = 10 \% \]
The Propeller Slip is 10%.
