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.

The next several problems utilize the same data given in this problem statement. I suggest you glance over the next few problems, so that you have an idea of the items you will need to calculate. You may determine that you calculate the items in an order other than that given on the test (doing this is OK!). BUT, be sure you look at EACH problem and provide the answer to that particular problem. Consider the bracket shown in Fig-3.
