Week 3 - Lecture 4
Momentum Transport
The flow of Falling Liquid
by Tan Ching Mun (16002662)
The objective of this lecture is to allow students to learn about:
- the setting-up of momentum balance over a thin shell of steady-flow liquid flowing down an inclined plane.
- the method of solving related flow parameters such as maximum velocity, average velocity and etc.

In this lecture, I learned about the derivation of momentum balance by analyzing the system. Besides that, AP Dr. Bawadi also taught us about the rule of thumb in determining the direction of the system if the coordinates are not given. By using our left hand, our thumb will represent the z-direction, the index finger as x-direction while the middle finger represents y-direction. Z-direction should be used as the direction of flow while y-direction should be protruding out of the paper/plane. After deriving the momentum flux balance and velocity profile over a thin shell of fluid for a steady flow, I think I am more confident in analyzing the systems in other directions or coordinate systems. However, I am still not really clear on how to solve the other questions starting from average velocity which involves double integration. I wish sir could give more examples and explanations for questions involving mathematical applications.Besides that, we had our first tutorial session on this week which is also a question related to falling liquid with different coordinate.
