What are the units for your flow rate?
And also, Your equation for area includes the term D^2 which implies the diameter is being squared, so your answer for area should have the units mm^2.

"If you speak while standing in a corner with your face toward the wall, you will sometimes notice that your voice sounds unusually loud. Explain."The Attempt at a Solution
Is this because the sound waves are bunched up when they bounce off the corner...
Thanks for the help. I found out my algebra is weaker than I thought. I am confused with how I can reduce all these divisions. For say equation A, I cannot see how to get all the a's on one side. For example, when b is subbed into a,

equation for h was (13.1044+7.24h + h^2)/a^2 + (1.0816-2.08k + k^2)/b^2 = 1
equation for k was (4.4521 - 4.22h + h^2)/a^2 + (3.3124 - 3.64k + k^2)/b^2 = 1
although i changed the coordinates in equation for h with a 0 to make it simpler. And I also didn't multiply out the squares in the...
when plugging b into the equation for a, I end up with as shown here, http://tinyurl.com/c2onxp7
then I simplified that down to
a = ((4.95-k)(4.83-h)(-0.56-h))/(2.2-k)
yes, however I changed the coordinates for equation h.
Here are my equations with the new, correct equation for h.

NOTE: the equations are not multiplied out like I did earlier, but it looks like you read them right.
I also tried working with wolfram alpha with this...
Homework Statement
I have four equations and have four variables. I need to solve for each of the variables. I am having difficulty figuring out how to do this.
My equations are here. http://imgur.com/EOA8I

Ok I got them here, http://imgur.com/2KL0g
the big K and little k are the same variable, i just wrote them like that sorry. Made a note of the missing k in the second equation and rewrote the number 7.66 for 7.66h in equation 4
I realize a matrix is used for this sort of thing sadly I don't...
I have x and y values. I plug the four different coordinates into the second equation and get four equations. Then I solve using quadratic for h and k, (a and b can be solved without quadratic I believe). Then start plugging them into one equation at a time correct?
Homework Statement
does anyone know how to solve this equation for just x?
x + x^2 = a^2*b^2 - 2.01j - j^2 - 15.132
it's possible right? because I'm trying to solve for four variables using four equations but two of my variables will have a first plus a second degree
