Fluid Mechanics 4.6 - Control Mass, Control Volume and Control Surface

This segment reviews the system, control mass, control volume, and control surface definitions. These definitions will be very important in modules 5, 6, and 7.

Module 4: Fluid Kinematics
This module is concerned with the fluid motion, excluding the forces necessary to produce the motion. We will consider the kinematics of the motion (velocity and acceleration) and the description and visualization of its motion. The analysis of the specific forces necessary to produce the motion (the dynamics of the motion) will be discussed in detail in the following modules. Importantly, this module introduces the Reynold's Transport Theorem, which is the basis of modules 5, 6, and 7.

Student Learning Outcomes:
After completing this module, you should be able to:
1) Discuss the differences between the Eulerian and Langrangian descriptions of fluid motion.
2) Identify various flow characteristics based on the velocity field.
3) Determine the streamline pattern and acceleration field, given a velocity field.
4) Discuss the differences between a system and a control volume.
5) Apply the Reynold's Transport Theorem and the material derivative. This material is based upon work supported by the National Science Foundation under Grant No. 2019664.
