what is microscopic and macroscopic vieuwpoints
Microscopic vieuwpoint describes material behavior by characterizing the behavior of atoms and molecules. It is useful for understanding phenomena susch as surface tension and viscosity.
Macroscopic vieuwpoints describes material behavoir without resulting to models at the atomic level. Its simpler and used more often.
-
What is the continuum assumption
fluid behaves as if it were comprised of continuous matter that is infinitely divisible into smaller and smaller parts
-
what is a fluid particle
Its a small quantity of fluid with fixed identity.
-
what is a fixed identity
It means that the particle is always comprised of the same matter.
-
1.8 Checking for dimensional homogeneity (DH)
-
When is the equation Dimensional Homogeneity (DH)?
When the primary dimensions of each term of a equation are the same
-
What is a dimensionless group?
It's any arrangement of variables in which the primary dimensions cancel. They are also called
-groups -
2 Fluid properties

For what is the bulk modulus of elasticity EV(kPa) used?
To characterize compressibility
-
what is the Mach number?
The Mach number is the ratio of the speed of the flowing fluid V to the speed at which sounds travels in the fluid c
-

What is the viscosity µ?
Its the fluid property that characterizes resistance to flow: shear stress/ rate of shear strain
-
What is the shear force Fs?
Shear force Fs is the net force on a body due to shear stress acting over the body

For my 1st exam I got a C. Then, I started looking for ways to learn better and I came across Study Smart. Since then I have scored a A+, A, A- and another A. I highly recommend it to everyone who wants to hear it. I am so happy with it!!
I was struggling to finish all my first-year subjects for 3 years. Then I discovered Study Smart, which helped me to finish all of them within 3 months.
Because of StudySmart, things are going well in many ways. Before, I always had study stress and no time for anything. Now I feel calm and confident (because of the program). I used to score a B, now I usually score an A or A+.
Hey Chris, I really want to thank you very much for developing the platform, I usually got around C for my exams, now I scored an A+, an A and a A- !!
Since using Study Smart, my average has increased significantly. I even completed a statistics course with a A+ while I'm bad at statistics. I took on extra courses this year, because of Study Smart. Thanks so much!
Ever since I started studying with StudySmart I passed all my exams !!! No more re-sits!! At first, I was happy with a pass and now I only get good grades. Many thanks!
I aced all the courses I studied with Study Smart. For law, I first scored a D, and now an A! I’m 100% sure that I’ll pass all the courses I study with Study Smart.
I always thought I studied well. My grades were fine. I could never have imagined that applying these study skills would have such a huge and direct impact on my grades, my speed and the pleasure I have in learning.
For the first time, I finally feel totally confident about the way I learn. I have the perfect overview and make great progress in terms of speed and the grades I get. Thanks, Chris!
I immediately started to enjoy learning again, and my grades soared. All of a sudden, everything went better. I highly recommend Study Smart to all students..
Being able to create my materials online made the process of studying so much smoother and quicker. I no longer have to spend a huge amount of my time on creating my summaries.
At first, my notes were a mess. Now I use Study Smart to take my notes in a perfectly structured way. It helps me to save a lot of time and do other things I enjoy.
Students that study with Study Smart get better grades. The system applies all the learning methods in such a way that both well-performing students and students who struggle perform much better.
Hi Chris, I would like to thank you very much. Last year I scored C on a course, and this year I got an A+ thanks to your method! Thank you very much!
The largest effect is that my child is more enthusiastic about school! Every parent wants their children to be happy at school, Study Smart made it happen.
In high school, I failed several exams, and that has really changed now. I actually needed this tool very much back then. Since I started studying with StudySmart, I haven't had any D's. My average score is now an A and those are results I would have never had in the past
With my old method, I passed only 3 out of 8 courses. Since I started taking my notes digitally in Study Smart, I have passed all my courses on the first try. For me, StudySmart takes away the stress of wondering if I will pass or not.
Thanks to StudySmart, I passed all my exams, and with better grades than before! On top of that, I have mastered a very good study method now, which I am confident will help me earn my degree.
