Hello! We focus on environmental engineering topics and discussions, including: FE review, groundwater monitoring, green infrastructure, environmental sustainability, and software simulations of these topics.
Hey I’m using the equation mentioned here 7:32 and when I’m solving for gamma my answer is coming out cos(-1.432) how is that possible. When my coordinates are (8 , 10.5)
In the FE reference handbook, there is an equation on pg. 297 called "circular pipe head loss equation" where Hf = [(4.73)(L) / (C^1.852)(D^4.87)] (Q^1.852). Can this equation be used here? My answer was [(4.73)(2000ft) / (120^1.852)(0.83^4.87)] (8^1.852) = 155.55 ft.
Side note. The background music in this is on point. I didn't even notice it until I turned the video up more, and even then it's just there enough to seemingly enhance focus with good tones and rhythm.
Hello, how do we know when to use the -k vs how you plugged the k value as a positive since the formula in the handbook has it show Co(exp(-kt))? Thank you for the videos! Very helpful.
Hi Fahmi, Glad you found the video useful. We mostly focus on the environmental impacts of power generation which are often covered in an Introduction to Environmental Engineering text. The basics of energy and mass balance related to power generation are typically covered in a text on elementary thermodynamics. The details of power generation are outside my field so I'm afraid I can't recommend a text specific to that subject.
have you ever read in real time data from a database that effects the fluid levels? Currently trying to make tanks that will have valves open and close beased on whats sent to a database from another source.
Hi Jacob, sounds like an interesting project. I've never used Unity to read in real-time data but that might make a good next project! Depending on what you're going for, you might consider creating your project in Node.js and use three.js for the visualization. At least making API calls would be more straight-forward. Let us know how the project goes or stop back by in a few weeks and maybe we'll have a new tutorial on real-time data integration! Thanks!
@@highwaterstudio1534 thanks for the reply! I'll actually be pulling from a Postgre SQL Database. having HMI and PLCs running simulations and sending that information to the database. trying to have the valves turn on and off by themselves with that information. This tutorial is a great start for me though so thanks! I'll be on the lookout for future videos.
Thank you so much for this video. It will probably be the main source for the robot arm i will try to make. I will try to implement all these equations to the arduino code on my own. So excited to start this project. Thanks again!
Thank you for the kind comment and good luck on your robot! Our first-year students build a similar project and many of them turned out well but it can be a challenge to get additional moving parts (like a claw and rotating base) all working together correctly. Feel free to let us know how it turns out!
Hello Cole, thank you for asking. One of the benefits of the unit hydrograph is that it can be applied to other storm events of similar duration without regard to the discharge data from which it was created. Once the hydrograph has been normalized to one inch, it can be scaled up or down to predict other events of similar duration. In other words, only multiply by the excess precipitation of interest, not the data from which the graph was constructed. Hope that helps but please let us know if you have any other questions.
Hello Cole, We divide by 150 acres to create a weighted average of the runoff coefficient. Since different areas of the watershed contribute runoff differently, the easiest way to calculate the entire watershed runoff is to calculate the weighted average runoff. So we multiply each area by its specific runoff coefficient and add them together, then divide by the total area (150 acres) which results in an average across the entire watershed. Hope that helps but please let us know if you have any additional questions.
Hello, Ryan, and thank you for your comment! After rechecking the calculation, I think you are correct that there’s a calculation error when calculating the hydraulic slope. I believe the error is in the calculation only and the formulas and concepts are still valid. I really appreciate you not only catching this error but also brining it to our attention. We hope you found the video otherwise helpful!
Hello, Amy, and thank you for your kind comment! I would be surprised to find a problem this complex and time consuming on the FE, however, they may simplify the problem by providing additional information. I did find a similar mass balance equation on page 319 of the FE handbook under the Fate and Transport section. There are solutions to linear differential equations starting on page 51, but they only cover the most straight-forward examples. I hope this helps and good luck on the exam!
Unfortunately, coal fired power plants are not very efficient. Depending on the form of generation (coal vs. solar, etc.) electric is not necessarily the same as green. Thanks for the comment!
Hi Annie, we hope you found the review useful. You can find decay rate equations for zero, first, and second order equations on page 324 of the reference material.
i wish you did this video from scratch. how you imported the assets, when you downloaded them from, how you combined the varies parts like valves, tanks and all
Thank you for your feedback, Winston! Receiving various perspectives from our audience helps us to plan future content. We're considering a multi-part mini-course which will bring together multiple aspects of Unity and engineering sciences. In the meantime, Unity Technologies maintains an extensive library of excellent, free tutorials/courses ranging from getting started to advanced features and concepts which you may find helpful. The models were purchased from Synty Studios who provide large bundles of commercial assets and occasionally have store-wide discounts if you're willing to wait for them.
Hi Limbasiya, I'm glad you found this tutorial useful. After some thought, I think I will write a tutorial on our website, highwaterstudio.com, which will include the code. I'll try to have this up by next week. Good luck with your project!
@@highwaterstudio1534 hello, thanks for uploading this video, its really helpful. Ill need the code too, but the link isnt working. Can you share it with me?
Thank you for your interest! I'm considering creating a more expansive system to put on Unity's Asset Store. If so, I'll definitely create a video announcing it.
@@highwaterstudio1534 Hi, could please tell me if finally you created the system and putted on Unity's Asset Store? if don't, can you recommend me a web site where I can find a simillar system: tank, valve and pipes. I am developing my master's degree final project developing an interacting laboratory for students. Thank you.
