Dear students,
First, I would like to welcome you all to the course of "Fluid Mechanics".
Second, I would like to announce that we will effectively commence the learning process through on-campus classes and online through Zoom (once needed), on Monday, January 30th, 2023. We will be having announcements, discussion forums, and assignments for each topic on Moodle. Never hesitate to add a comment and/or add your query through the messages icon on Moodle.
Let the journey begin and let us enjoy it!!
Stay tuned and kindly notify all your peers.

A quantity of interest in the analysis of pipe flow is the pressure drop since it is directly related to the power requirements of the fan or pump to maintain flow.
-
There are two main types of fluid flow - laminar flow, in which the fluid flows smoothly in layers, and turbulent flow, which is characterized by chaotic motion and large amounts of mixing. In this video, Efficient Engineer Channel explores the differences between these two flow regimes. It covers how Reynolds number can be used to predict which flow regime will occur for a specific set of flow conditions. And it will look at laminar and turbulent flows in pipes, and how the flow regime affects the pressure drop in a pipe. It willl also investigate why it is so difficult to simulate turbulent flow, and look at some of the different Computational Fluid Dynamics methods which can be used to simulate it.

Irrigation demonstration at Miami Dade College Kendall Campus shows that smaller pipe size diameter causes reduced water pressure. This can reduce irrigation sprinkler head coverage, reduce irrigation uniformity, and reduce efficiency. -
Water pressure is reduced by irrigation flow, especially in too small pipe size. The irrigation designer must use the friction loss chart and the sprinkler head table to estimate flow and pressure loss and select the right size pipe.
-
What factors affect how liquids flow through pipes?
Engineers use equations to help us understand the pressure and flow rates in pipes. Pipe systems are important to us, so it is critical that we can design them to carry the right amount of flow without too much drop in pressure from one end to the other.

If you have ever seen flowing water look frozen like glass, that's Laminar flow.
