a) Hydraulic systems commonly have a pump that produces a constant flow rate. Assuming the fluid is incompressible, this situation is known as steady flow or continuity flow. Referring to Figure Q3 (c) the fluid flows at a velocity of 3 m/min at point Q1. The diameter at point Q1 is 50 mm and the diameter at point 2 is 40 mm. In applying the continuity equations, determine the flow velocity at point Q2. Further determine the flow rate in g.p.m (gallon per minute), given 1 gallon = 0.00378 m³. %3D 2

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.
