dont you just hate it when you are working on something and the problem is horribly laid out. I am doing some stuff for school right now and the professor assigned 3 problems. I am pretty sure he did not give us enough info to solve any of them. GAH!!! /rant
2. For two dates in spring, soil water content was determined as follows. Calculate the equivalent depth of water stored in soil profiles on each of these two dates. Also, calculate the depth of water that has been gained or lost from the soil profile between those two dates. Volumetric water content Depth, April 1, June 16 5, 0.249, 0.062 15, 0.255, 0.105 30, 0.258, 0.140 45, 0.272, 0.161 60, 0.275, 0.188 75, 0.313, 0.235 90, 0.313, 0.274 105, 0.313, 0.313
Paging wall of tvs. You're needed in the OffTopic. Paging Dr. Maths aka walloftvs. You are needed in the OffTopic.
I think i figured it out. if not i just did it completely wrong. this is for Contaminant Hydrology, you are looking at a data table showing the volumetric water content of soil at certain depths. What i did was that the section of soil (depth2-depth1) so teh first one is 5cm the second is 10cm, third is 15cm and so on. then multiply that number by the water content in the cell. ie. 1st cell for april. 5cm^3 of soil x .249 water content = 1.25cm^3 of water present. i guess it ended up being really easy, still kind of puzzled with the unit exchanges using (cm^3)/(cm^3) i was looking to far into after i did the first problem: 1. Given the following soil water content distribution, calculate the depth of water penetration for a 24 hr and 5 day 2 year storms at St. Paul, MN. Depth (cm) Wi (g/g) ?b (g/cm3) ?v (cm3/ cm3) Water Needed (cm) Water left (cm) 0-20 0.05 1.2 20-60 0.1 1.3 60-100 0.15 1.4 100-200 0.17 1.4 Hint: Please use the graphs I gave you for probability of precipitation in Minnesota to estimate 24 hr and 5 day 2 year storm values. so yeah... lotsa fun. onto question 3 now. heres number 3: 3. A soil has an initial water content of 0.12 cm3 cm-3. How deep will the 5 cm of rain penetrate the soil if we assume (a) water moves to the next layer only if the layer above is saturated, or (b) water moves to the next layer over and above the field capacity water content? Assume saturation occurs at 0.50 cm3 cm-3 and field capacity water content is 0.40 cm3 cm-3.
God, i hate math! I am taking Calc I and i am in pain from it. I just took a test and got a 61 out of a 100 on it. I was really thinking that i was going to get 20-40%. The average in that class was 69%.
Calc 1 is a fun one. Do you need to take calc 2? i just took that in the spring. man what a nightmare. i managed to pull of a passing grade somehow, i have no clue how. the curve is your friend in calc. the final for calc 2, a B was 240pts out of 600pts. yeah... good try. I just finished. the third problem seems WAY to easy. hopefully i did it right. part a. (.5-.12) x 5cm = 13.16 part b. (.4-.12) x 5cm = 17.86
For my major(International Management) i only need to take calc I. I understand most of the stuff its just algebra whats holding me back. Back in russia i was a total slacker and never did any work at school, so no i am paying for it BIG TiME.
