Fluid Mechanics  A horizontal jet of water exits a nozzle with a uniform velocity of Vj = 20 m/s and area of Aj= 3 cm^2, and strikes a flat plate that moves to the right at velocity of Vc = 15 m/s. Upon impinging the plate, the jet splits into an equal upward and downward half-jet. (i.e. A1 = A2 = 0.5Aj). Neglecting gravity and viscous forces, determine the force (in both x - and y - directions) required to keep the plate moving at a constant velocity.

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.
