But the closer the speed approaches the hull speed, the greater increase in power is required for a given increase in speed. As an example, a 32-foot LWL displacement boat can be driven in calm water close to its hull speed by an engine of less than 20 HP. At around 75% of hull speed, its optimal cruising speed, the boat is very efficient. Beyond this point, as the second wave approaches the

• The speed of the rotor (Tip Speed in Metres per Second). • The size of the feed material. • The ratio of Bi-Flow® material to rotor throughput. Other influencing factors to consider for general crushing duties are: • High tip speeds generally result in higher wear rates within the rotor and crusher.

It is generally assumed to be a function of both tip-speed ratio and pitch angle. Below is a plot of the variation of the power coefficient with variations in the tip-speed ratio when the pitch is held constant:
