Bab 2:Fluid Application Part 2
Asslamamulaikum w.m.t
First and foremost. I would like to introduce myself who create this discussion. My name is Muhammad Naqeeb Bin Saiful Jefri and I'm currently studying at Politeknik Sultan Mizan Zainal Abidin in Terengganu😁. I'm the chosen one to discuss this topic by being the representative for Mechatronic Engineering students class of June 2019 session from DEM2S1😊. This task was about Fluid Dynamics and handed by Mr. Roshaizul Nizam Bin Sani.
There is some type of flow:
4.1 type of flow
section, but for each cross-section they do not change with time. Example: a
wave travelling along a channel.
each successive cross-section. Example: flow through a pipe of uniform bore running completely full.
move in an orderly manner and retain the same relative positions in
successive cross-sections.
Turbulent flow is a non steady flow in which the particles of fluid move in a
disorderly manner, occupying different relative positions in successive cross-
sections.
4.2 Discharge and Mass Flowrate
called the discharge. It is measured in cubic meter per second, or similar units
and denoted by Q.
the mass flow rate. It is measured in kilogram per second, or similar units and
denoted by •
m .
4.3 continuity equation
For continuity of flow in any system of fluid flow, the total amount of fluid
entering the system must equal the amount leaving the system. This occurs in
the case of uniform flow and steady flow.
direction. By the continuity principle, the discharge must be the same at each
section. The mass going into the pipe is equal to the mass going out of the
pipe.
Discharge at section1=Discharge at section2
Q1 = Q2
A1 V1=A2 V2
Another example in the use of the continuity principle is to determine the
velocities in pipes coming from a junction.
Total discharge into the junction = Total discharge out of the junction
Q1 = Q2 + Q3
A1v1 = A2v2 + A3v3
This is what I can compile for this period of time. Sorry if mistaken was done. Will try my best to do better in the future.Makan cekelat sakit gigi, ade masa jumpa lagi😂. See ya in bits. And goodluck to you lads students.
Sekian disini thank u guys...... 👍🏻

- Steady flow

- Uniform flow

- Laminar flow

successive cross-sections.
- Turbulent flow
Turbulent flow is a non steady flow in which the particles of fluid move in a
disorderly manner, occupying different relative positions in successive cross-
sections.
4.2 Discharge and Mass Flowrate
The volume of liquid passing through a given cross-section in unit time is

and denoted by Q.
The mass of fluid passing through a given cross section in unit time is called
- Mass flowrate

4.3 continuity equation
For continuity of flow in any system of fluid flow, the total amount of fluid
entering the system must equal the amount leaving the system. This occurs in
the case of uniform flow and steady flow.
- Application
We can apply the principle of continuity to pipes with cross sections that have changes along their length. Consider the diagram below of a pipe with a contraction.
A liquid is flowing from left to right and the pipe is narrowing in the same
direction. By the continuity principle, the discharge must be the same at each
section. The mass going into the pipe is equal to the mass going out of the
pipe.
Discharge at section1=Discharge at section2
