Hi, everyone.
- 00:02 - 00:04
I am rehab
- 00:04 - 00:05
from Sudan.
- 00:05 - 00:09
I am a master's degree holder in mechanical engineering.
- 00:09 - 00:11
I graduated from University of Khartoum
- 00:12 - 00:14
Faculty of engineering and architecture.
- 00:15 - 00:18
After graduation, I worked as a teacher assistant.
- 00:19 - 00:19
Um
- 00:20 - 00:22
uh, mechanical engineering department.
- 00:23 - 00:26
I like painting and reading books.
- 00:26 - 00:30
My favourite writers are Diner Street and Sidney Sheldon.
- 00:31 - 00:35
The last book I read was the Property of a Noblewoman,
- 00:35 - 00:40
and it is written by Sidney Sheldon. Sorry by Diners Steel.
- 00:41 - 00:46
And it is a storey of a noble lady who was happily married but
- 00:47 - 00:49
badly treated by her parents.
- 00:49 - 00:49
It's a
- 00:50 - 00:52
it's kind of a sad storey.
- 00:53 - 00:54
Anyway,
- 00:54 - 00:55
in the meeting
- 00:55 - 00:57
I in the meeting chat
- 00:58 - 00:59
I
- 01:00 - 01:04
I left a link to a Google document
- 01:04 - 01:08
where you will write five impressive things about yourself
- 01:09 - 01:11
this semester. I will teach you,
- 01:12 - 01:14
um, thermodynamics,
- 01:14 - 01:18
mainly the laws of thermodynamics and their applications.
- 01:19 - 01:24
It's an exciting course because you will study the fundamentals of
- 01:24 - 01:26
all the vehicles you see around
- 01:27 - 01:32
the road, such as cars, trucks, planes
- 01:32 - 01:35
and even drugs, rockets,
- 01:36 - 01:42
all contained engines. Um, they are driven by by engines.
- 01:43 - 01:46
Here is a quick review of your arm
- 01:46 - 01:51
of your in the screen. There is a quick review of your course
- 01:52 - 01:53
we will take,
- 01:54 - 01:58
um, it is presented on your screen. Yes,
- 01:59 - 02:00
we are.
- 02:00 - 02:05
We will be familiar with the first law of thermodynamics, and, uh,
- 02:05 - 02:12
we are going to take human metabolism as an example of for the first law,
- 02:12 - 02:18
the second law of thermodynamics is based on the study of heat engines.
- 02:18 - 02:21
Uh, heat engine is, uh,
- 02:21 - 02:25
the heat engine is, uh, any device, um,
- 02:25 - 02:29
that changes heat energy into mechanical energy
- 02:29 - 02:32
and the internal combustion engine. Another word.
- 02:32 - 02:37
Another name for a piston engine is the original variant
- 02:37 - 02:41
of the four stroke engine six stock engine and that battery
- 02:42 - 02:42
engine.
- 02:43 - 02:48
Next, we are going to This is about the second law and the heat engines.
- 02:49 - 02:50
And
- 02:50 - 02:53
next, we are going to understand,
- 02:54 - 03:02
uh, we are going to understand the principles of the 44 stroke engines, um,
- 03:02 - 03:08
ending and how to calculate the efficiency of the machines, the efficiency of them.
- 03:08 - 03:09
Uh, any machines.
- 03:10 - 03:10
Okay.
- 03:10 - 03:15
After that, we are going to study the heat transfer, uh,
- 03:15 - 03:20
principles in air conditioning, refrigeration and heat pumps.
- 03:20 - 03:25
Then comes the unavailability of energy or heat death.
- 03:26 - 03:33
And it is the prediction when the heat flows from high from high, uh,
- 03:33 - 03:37
high temperature region to low temperature region.
- 03:37 - 03:43
Until both areas are the same, they will have the same temperature.
- 03:43 - 03:48
In this case, we name it as, uh, death. Finally,
- 03:49 - 03:52
Finally, we are going to,
- 03:52 - 03:55
um, to deal with an important,
- 03:55 - 04:00
um document, which is the thermal pollution
- 04:00 - 04:02
and how it affects the Earth
- 04:03 - 04:05
and the causes of the global warming.
- 04:06 - 04:12
Then, uh, this is about the course. Then we move forward to the class procedure,
- 04:13 - 04:14
the class procedure.
- 04:14 - 04:17
I will send you the reading material
- 04:17 - 04:20
or reading literature of your lesson beforehand.
- 04:20 - 04:27
One day before the lecture, you need to prepare your lesson and and any queries, uh,
- 04:27 - 04:29
inquiries you have.
- 04:29 - 04:31
I'll clear it out for you.
- 04:31 - 04:35
They on the day of the on the day of the lecture.
- 04:35 - 04:41
Then I will record the course and post it on your Google classroom during,
- 04:41 - 04:44
uh after the class.
- 04:44 - 04:47
So it will be easy for you to go back through it at
- 04:47 - 04:52
any at your at your own pace whenever it is convenient for you.
- 04:52 - 04:55
My advice is to take notes.
- 04:55 - 05:00
Please send me your written roads after each class section for revision
- 05:00 - 05:07
and the best one I will post on the class on the class online bulletin board,
- 05:07 - 05:09
which is called Post in my World
- 05:09 - 05:10
and
- 05:11 - 05:12
Boston. My war.
- 05:13 - 05:14
Yes.
- 05:15 - 05:17
Um, it is going to be,
- 05:17 - 05:19
uh, this one.
- 05:20 - 05:26
This is, uh, here on the on your screen. As you can see, this is the link for the pasta.
- 05:26 - 05:31
For the for your bulletin board and hear how it looks like it is.
- 05:31 - 05:34
This is thermodynamic post in my world.
- 05:34 - 05:36
It is a bulletin board.
- 05:37 - 05:39
Okay, it is.
- 05:40 - 05:43
Um it is a bulletin board and interactive board
- 05:43 - 05:46
in which you you will posture your questions,
- 05:47 - 05:51
commence reflections and suggestions on this bulletin.
- 05:51 - 05:56
And I will I would like to you to feel free to ask any questions,
- 05:56 - 06:01
or you can answer any of your peers questions
- 06:01 - 06:03
I can't wait to hear from you.
- 06:03 - 06:06
We will also have a group study.
- 06:07 - 06:13
Um uh, we were going to have a groups that study groups I mean and group,
- 06:14 - 06:18
uh, projects as well as, uh, study discussions.
- 06:18 - 06:21
The group discussions will be, uh,
- 06:21 - 06:27
in the class will be face to face in class or online on the part of the same public.
- 06:27 - 06:30
It's your option. They are all optional.
- 06:31 - 06:33
The last in the last minute of your
- 06:34 - 06:41
of your in each class, Uh, at the last lesson, Uh, last minute, I mean, on each class,
- 06:41 - 06:45
there was going to be a short quiz regarding the lessons topic.
- 06:45 - 06:52
It could be a question or a question about an image or video or forum.
- 06:53 - 06:57
And you are going to have also, uh, formative assessment.
- 06:57 - 07:02
Uh, this is going to be at the midterm after five weeks from now.
- 07:02 - 07:05
And two formative assessments.
- 07:05 - 07:09
One after two weeks from now and the other one at the end of the semester.
- 07:10 - 07:18
Finally, comes the learning contact. You need to you need to, uh,
- 07:19 - 07:22
to respect this learning. Uh, learning contract.
- 07:23 - 07:29
First point is respect. You should respect all the diversities in class.
- 07:29 - 07:32
Your classmates, regardless of their age, culture,
- 07:32 - 07:37
skin colour, backgrounds or any natural defective.
- 07:38 - 07:40
Uh, next is the attendance.
- 07:41 - 07:47
Uh, your attendance should be at least around 85% of your whole attendance.
- 07:47 - 07:51
Avoid being absent or stay to stay up.
- 07:51 - 07:57
Um, avoid being absent to stay up to date, and you do not miss any classes.
- 07:57 - 08:00
Next is your class participation.
- 08:00 - 08:03
And this, uh, your class participation.
- 08:03 - 08:09
You should contribute at least once or twice in the class discussions,
- 08:09 - 08:11
whether in the public or
- 08:12 - 08:13
um in classroom
- 08:14 - 08:17
and whatever, Whatever. It is convenient for you
- 08:18 - 08:22
next time reading. And you should read the reading material.
- 08:22 - 08:26
Uh, I will send and prepare your lesson beforehand.
- 08:26 - 08:29
Uh, number five is your the groups.
- 08:29 - 08:34
You should, of course, respect your, uh,
- 08:34 - 08:37
group members support them and communicate with them,
- 08:37 - 08:40
whether in the study group or the
- 08:40 - 08:43
project group and share responsibilities equally.
- 08:44 - 08:47
Next, is that the individual? Uh,
- 08:47 - 08:49
the individual, um
- 08:50 - 08:50
wow.
- 08:51 - 08:57
Assignments or a study? You should assign a few hours every day to study.
- 08:57 - 09:03
And hence you should meet your deadlines for your assignments.
- 09:03 - 09:06
The last point for your learning contract is help.
- 09:07 - 09:11
You should ask whenever you want, whenever you need.
- 09:11 - 09:13
You should ask help
- 09:13 - 09:20
through poster on my wall or paddling or else in my office during during office time.
- 09:21 - 09:24
And that's it. That's it all.
- 09:24 - 09:25
Um,
- 09:25 - 09:28
that's all, folks. And
- 09:28 - 09:29
see you soon.
- 09:29 - 09:31
I'm looking forward,
- 09:31 - 09:35
uh, to enjoy teaching you this semester.
- 09:35 - 09:43
And if you have any any queries or anything, please don't hesitate. Come forward.
- 09:44 - 09:45
See you soon.
