Fluid Kinematics

The branch of science that deals with objects which are either in motion or stationary are studied under the branch of classical mechanics. Fluid mechanics is a subcategory of classical mechanics that deals with the behavior of fluids at rest (fluid statics) or in motion (posing some velocity). In fluid kinematics, studies focus on the associated motion of fluid particles or groups of particles, and its associated parameters like displacements, velocity, and acceleration without concerning about the forces that caused the motion. All the laws of classical mechanics are applied in the study of fluid kinematics.

Consider a helicopter flying in a straight path at a speed of 52 m/s. The the rotor diameter is 10 m and the rotors are moving at 264 RPM (revolutions per minute). What is the maximum rotor tip speed (in m/s). Hint: Note that the rotor will sometime be moving in the direction of the flight path and at other times opposite to the flight path or at an angle to the flight path. The maximum rotor tip speed is generated when the rotor is moving in the direction of the flight path.
