#2: D1 or D2 Water Distribution Math Practice
Vložit
- čas přidán 5. 09. 2024
- In studying for my State Exam I taught myself, with a little guidance from the book, how to solve these types of problems in what seems to be a different type of way than the other common schools of thought that I have found out there on the inter webs, or even my work place.
I, of course, find it most user friendly. Case study of one . . . Me! Haha.
Let me know what you think!
Thank you,

At 08:52 you say to divide 8.34 by 5. It should be the other way around... Divide 5 by 8.34. Your solution (0.6gal) is correct.
About to start for my D1 and just watching these I’m lost lol
Taking my WDM1 today here in WA. Unfortunately I’ve given it a few tries already and literally within grasp of passing.. 68% High 60’s 🤦🏻♂️ see how it goes today! Appreciate the break down!
howd it go??
Can't you just find the volume which is MGD of the 200 gallons then multiply 150 x 8.34 lbs? It saves all that converting?
There are easier ways to the solution yes. But I find those to be kind of cheater ways.
The point of the example is to showcase the power of understanding the very simple and fun process of conversions.
With that talent in your tool belt you can figure out what ever inoculation problem you might come across.
A pipeline is dosed at 50ppm,using the continuous feed method with 12% sodium hyop chlorite. If the pipe is 18" and it is filled at 1fps, what is the feed rate in gallons per hour?
Hello, I need help with a problem. How long would it take to empty a tank that's 28' H and 28' radius, at rate 2cfs through an 8" pipe.
Bro you are making it more confusing. I appreciate the effort though. Thanx for trying to help 👍🏻
Can ya solve this! I’m stuck! How many gallons of water are in the reservoir if a well pumped into an empty reservoir for 12 hours through a 12 inch pipe, with a velocity of 2 ft./s. ❤
How do you calculate feed rate in gallons per hour?
Do you have to remember the unit conversions or will their be a chart to tell you the value of each unit for the exam
There will be a chart with all the conversation and formulas you will need for the math. I just got my D1
Tried googling it but couldn't find the answer. How much time do they give you while taking the exam?
Usually 3 hours
@@danielg201286 thanks
I'm starting my sac State course today. I'd like to know how many math questions are on the licensing exam?
Out of 100 questions the last 25 are math and you need a 70% to pass
Hey man thank you for being cool and helping. Alot of people just put up videos and don't respond. I appreciate it. Your licensed in California?
@@richarddenny3897 no problem! Ya I’m licensed here in California
As of today it was the last 15 questions. Worth 2 points each.
Could you tutor me ?
actually Elias i work a full time job so tutoring consistently would be a little too much to take on. But if or when you have issues post them here and I will do my best to tutor you through them either by replying to your comment, or making a whole new video! Thank you for asking!
How many questions can be missed?
30% if I remember correctly. I believe a 70% or better will pass but it might actually even be as low as 60%
correction. You need a 70% to pass
Oregon d1 test was not fun.
What did you find the most difficult? Any areas that blind sided you?
terrible way of doing it... the c1v1=c2v2 formula method is so much more straight forward.
Not everyone is a good teacher.
Not everyone is a good student.
