  1. It's a fairly large part of the afternoon. Doing accurate conversions and utilizing the flow-rate of solids equation will take you a long way but just depends on this particular exam. Mine had a good deal of the chemistry aspect as well.
  2. @saraxoYeah long way for me to just say take the avg. lol
  3. Using above methodology the 25 year storms curve would be just slightly above the 20 year storm which is incorrect. In reality it would be roughly half way between the 20 and 50 year events. From the chart I get 20 = 5.8, 50 = 6.9 (6.9-5.8)/2=.55 (average) 5.8+.55=6.35 (20 yr event + avg.) Reason being that the curve is based on the probability of that storms recurrence and not just the difference in years. A 25 year storms chance of recurrence is somewhere in the vicinity of halfway between a 20 and 50. Hope this helps.
  4. Oh okay. To better visualize this assume you have 2 identical unit hydrographs in the same plot. The first begins at T=0. The second doesn't begin until T=12. Therefore when when the second hydrograph reaches T=15 it has only been producing runoff for 3 hours. Soooo those are supposed to be identical curves. Excuse the picture. I'm an engineer not an artist lol. Hope this helps.
  5. Okay so I'm assuming you are just looking for an explanation on the scaling? If not please let me know. So to get the solution they went to the hydrograph constructed based on the 4.37 cm precip and found Q = 35 m^3/s at 15 hrs and 10 m^3/s at 3 hrs. Keeping in mind these values are for 4.37 cm you have to scale each value so for the 5 cm event 5/4.37 = 1.14 or 114% ( I like to think of them in percentages). Replicated for the 12 cm event 12/4.37 = 2.75 or 275%. Q = 35*1.14 + 10*2.75 Q = 67.5 I feel like I just rewrote their solution but just a little more in my mindset. Point being you have runoff values based on the 4.37 event but the events you are calculating are some degree different so you have to scale for the variance. Vice versa you could say @ 15 hrs you get 35/4.37 = 8 so you get (8 m^3/s) per cm and @ 3 hrs you get 10/4.37 = 2.29 (m^3/s) per cm then multiplied those values by your corresponding storm events. Hope this helps. Please let me know if you have any further questions.
  6. I don't have that exact book but if you would like to explain your problem and question I bet me or someone else could help you out.
  7. that I'll hang around as long as she would let me
  8. She was being detained for making moonshine but managed to escape.
  9. Stuff like this is just a little annoying to me coming from the heart of oilfield country. Everyone is an "engineer" in the oilfield no matter what they actually do. I know I'm probably being Petty Mayonnaise on this but still bugs me.
  10. Agree 100%. Loved the book. Movie doesn't do it justice. The book had some really cool 80's nostalgia and the characters seemed to appreciate it. Movie they were just in it for the contest. Kinda took the fun out of it for me.

    I think your state board would be the best reference for this. So many differences from state to state.
  12. I've been playing the Beta. I think it really requires a group to play. I have a few buddies playing and when fate actually aligns and we can all be online at the same time it has been fun. Playing solo it's hard to get anything done. It's a fun game but I've already started playing BFV more.
