Who knows how to do Index of Qualitative Variation(IQV)?
1 Attachment(s)
Math noob/boob here:
In attached document its problem 4, part B. To calculate the IQV we: k(N2 – S f2 ) N2 (k-1) (those 2's are squared not 2) |
Number 5 c is killing me too because I can't figure out how to make a frequency bar graph in excel.
|
You can google stuff on excel and figure out how to make a bar graph. I've done that before, so anyone can do it. :)
As for 4b, dunno. What's your major? |

Figured out 5c. Just cheated and input the information without using the excel formula.

42.

Answer to everything kthx |
omg I've been trying to calculate the mass flow rate of ocean water across a heat exchanger for a reheat Rankine cycle and I was lost. 42 kg/s it is!!!
|
no way!
I was sitting here trying to calculate how many beers it would take for me to try and pretend like I remembered a single thing from my college quant classes, and I got 42 also! |
No problem guys, I am a mere good samaritan...

Moral of the Story : Math makes me want to quit school.
|
I had a teacher tell me in HS, "He who has the math has the money". So I'm retaking Cal 4. :) And DE... Kicking ass in my other classes though. Doing a regenerative cycle in thermo II right now, and almost got it. I think..
|
Just in case anyone was curious I got a thermal efficiency of 35.8%. But that's an ideal case of course, neglecting the turbine and two pump's efficiencies.
|
I had a doctor tell me once "the sloppier the handwriting, the more money the person makes." Seemed to be working for him.

p.s. teach gave the whole class an extension today because he had been on conference and unable to answer questions. I asked him today, and he showed me. He wanted me to make up the frequencies to show the highest/lowest variation. After I found out he wanted us to fabricate the math, I copied from this cute girl who sits next to me. |
