Ok, The manual for this software is stupid. I know that the table is right so it might be from the number of atoms. Can you tell me how would i go about doing that

Picture

I tried but wasnt able to do it . This is basically the table i want. if i take the number density of O2 and divide by the total i get 66 %. so basically i can either get the number density or this percentage.http://imgur.com/a/2M4HH

ok let's try to find the atom percent because the answer is given as ~66 percent oxygen, so that might be an option. because it's definitely not 88 % one. So how do i get that?

The thing is that since its UO2, somehow in the answer I am given, U and O and O are divivded out of 100. So O2 is equal to ~66 percent. and as i increase the U-235 content Uranium mass percent increases from the basic ~33.33 percent, and the penalty of that is received by O2 mass percent. The...

I got that what do i do after that

Homework Statement Hello guys, I was using mcnp code SERPENT, and while defining materials i encountered a problem. The problem is that for example: if I'm given that i have a 3.5 percent enriched U-235. how do i find the rest of the mass percents of U-234, U-238, O2. Now since i know mass...

I tried solving it using y=o, when u=0 and y=h/2 when u=0. still I am not able to find the same answer.. can someone tell me what's wrong attempt jpeg: http://postimg.org/image/u2srvitj7/

a step by step solution would be awesome, since this is the beginning and i want to understand the basic concept ruling these equations. i have watched videos online everywhere but can't get to the last (1-(2h/y)^2) part

Homework Statement Fluid flows between 2 parallel plates, flow is fully developed and laminar, the distance between the plates is h In the notes there is a general form of solution after integrating it 2 times. where a is h. but i saw in the book that we have to get +h/2 and -h/2 then add...
