Propeller Law: The Propeller Law is an idealized set of assumptions that can be used for boats operating in the displacement mode below the Hull Speed. These assumptions are:
The constant, C_{n}, can be found for any of the equations above if the two other values in the equation are known. For example, if PSModel predicts a propeller thrust of 50.0 lbs at a boat speed of 8.0 MPH then C_{2} can be determined as follows:
Once C_{2} is known, the entire curve representing MPH vs. Thrust can be plotted.
