Hello Guys, I just want to say fluid mechanics and hydrology are one my favorite subjects in civil engineering 😊 ! What is your favorite topic in engineering?
enGENIEer pumping systems from multiple pumps to multiple outlets which I model on my Pipeflow software. Currently modelling a new water supply for Tamale in Ghana.
Hi Ella! Thank you for watching. We're really glad to be able to help. Best of luck with your FE and don't hesitate to contact us at hello@genieprep.com if there is anything we can do to help.
No problem! Thank you for watching and for being here. make sure you sign up for some free practice problems at www.engenieer.com! Good luck with your studying!
How you actually know which equation to use or which section to go when you read a problem? I keep forgetting what i study for last topic. What should I do?
I wish I had found these videos when I took the FE my first time. My second time is tomorrow, and I feel even less prepared than before. However your videos are really helpful, so here's to hoping I won't have to take it a third time!
Hi Phil, that's a great question and I am not really sure why they're not providing the energy equation on the reference handbook, but just make sure you add it to your cheat sheet and remember it for your FE. I hope this helps and thanks for watching!
Here is a video, where bernoulli is expressed in head, ruclips.net/video/yNcCaSc7qvo/видео.html. However, I don't have videos on energy per unit mass and energy per unit volume, yet! Thank you for watching!
I am confused when you use the continuity eq. Q=V1 x A1=V2 x A2 because based on the previous equation V1=0, so Q should be 0 if we assume V1=0. Or not? Thanks!
Actually V1 is not zero, stricto sensu. (V1/V2) is close enough to 0. So, if you had the diameter of the reservoir, you could even compute V1, and then put this value into the Bernoulli Eq. It happens that this value squared (V1²/2g) of order of magnitude, say, 1e-8 or so, is gonna end up being neglectable in the equation.
It doesn't matter how you choose your datum. If you use the datum at point 1, Z1 will be zero and Z2 will be -42, if you rearrange the equation, you should get the same answer as shown in the video. I hope this make sense and good luck.
Hello, I just wanted to know what device you use to work on these problems, meaning; are you using an iPad, or any other device to work on the problems? Thanks!
Hello Mostafizur, I hope studying is going well! I just want to let you know that I am still doing the "Problem a day series" on Patreon, www.patreon.com/enGENIEer. You can also ask me what kind of questions you would like to see next on patreon. There are already two questions that I have posted so far exclusively for my patreon supporters and a video on topics you should focus on for Geotechnical engineering. I hope you enjoy it, thank you 😊 and good luck!
Hello Gustavo, I have some videos on economy but I will post some more in the future! I will also post some videos on statistics as well! Good luck with your studying!
Fe Handbook version 9.4 has been updated to version 9.5 in August 2018. The equation on page 104 (FE Handbook 9.4), while it is on page 109 (FE Handbook 9.5)
Hello Yoona, correct! So in these problems, we usually calculate for the gage pressure. The absolute pressure P = Pg (gage pressure) + Patm. If you substitute the absolute pressure equation for P1 and P2 (at the open surfaces), the Patm cancels and that is why Patm is usually considered zero! I hope this helps, thank you for watching and good luck with your studying!
That's what I learnt from my professor, thank you so much ma'am😇 by the way next sem em gonna take hydrology. Will definitely watch more videos from you😊

Structural and Hydro are my favorite
This is great! A flood of memories are coming back from my fluids class in college.
Awesome! Glad you're enjoying it! Keep up the great work!! 😁
Very good job! Thank you for sharing your interest in teaching :) Taking the FE in a few days and your efforts are making a big difference.
Thank you Patricia! Good luck with your exam and I hope you do well 😊
Thank you so much for helping people! You are amazing!
Hi Ella! Thank you for watching. We're really glad to be able to help. Best of luck with your FE and don't hesitate to contact us at hello@genieprep.com if there is anything we can do to help.
I learn more from your videos than class! You are awesome
Engineering can be challenging, especially when we don't end up with the greatest professors. But I am glad I can help 😊 and Keep up the good work!
Thank you so much for those problems in uscs units I almost forget about them. Thanks again 😊

Thank you Zaraki!

Hello, thank you for your comment and I really hope you passed! Good luck.
Hi, how was your test? Do you have any recommendations for those who are studying for it?
Very helpful, thank you
Very Helpful Thanks a lot
Why isn’t fluid energy equations in the FE reference handbook ? In regards to converting frictional head loss to specific energy
Hi Phil, that's a great question and I am not really sure why they're not providing the energy equation on the reference handbook, but just make sure you add it to your cheat sheet and remember it for your FE. I hope this helps and thanks for watching!
Control Systems. You are awesome.
Most excellent!
Awesome video, thank you!

Is there any video on expressing bernaullis eqn in terms of head, energy per unit mass, and energy per unit volume
Here is a video, where bernoulli is expressed in head, ruclips.net/video/yNcCaSc7qvo/видео.html. However, I don't have videos on energy per unit mass and energy per unit volume, yet! Thank you for watching!
Can u just give me expressions for bernaullis eqn in terms of energy per unit mass and energy per unit volume
why kinetic head at that point (2) is considered if it is already incorporated in total head loss as minor head loss at exit?

Hi, I have a problem I need to solve, apparently simple but I have no idea how to go about and solve it. What is your hourly rate? Thanks

You are the best
Thank you
How you choose the Datum? What if I choose the Datim at point 1? I would have a different sign, and I would get a wrong result.
It doesn't matter how you choose your datum. If you use the datum at point 1, Z1 will be zero and Z2 will be -42, if you rearrange the equation, you should get the same answer as shown in the video. I hope this make sense and good luck.
meri beaucoup! trop beau contenu.

Pressure 1 is not zero, it's atmospheric. The gauge pressure at 1 is zero, and Bernoulli's eqn is based on guage pressures

Hi, do you cover economy and statistics as well?
Merci
Hello Gustavo, I have some videos on economy but I will post some more in the future! I will also post some videos on statistics as well! Good luck with your studying!
enGENIEer thank you for all your effort.
I don't think the continuity equation is on page 109, my book has it on 104... Is 2018 manual not the most up to date?
Hello, that is actually weird. I have the PDF file, do you have a PDF file as well or do you have a hard copy? On the PDF file, I have it on page 109.
@@Genieprep I have a PDF... Strange...

P=0 because it's exposed at the atmospheric pressure.
