- mathgroup,
- I need your help on the following problem.I have 8 equations as
- follows:
- a=P*mcp*ac*tc*tf*tr
- b=P*mcp*(4*ac*tc*tf+ac*tc*tr+2*af*tc*tr-ac*tf*tr+ac*l*tc*tf*tr)
- c=P*mcp*(4*ac*tc+4*af*tc+l*4*ac*tc*tf+l*ac*tc*tr+2*l*af*tc*tr-l*ac*tf*tr)
- d=.....
- "
- "
- "
- h=..............
-
- I need to solve these equations simultaneously for "ac" in terms of a,b,c,d,
- e,f,g & h. So, here i need to eliminate the other variables like P, mcp, tc,
- tf, tr, l, L, af, etc.
- I am using mathematica and tried the commands eliminate (but my PC ran out
- of memory before giving me the solution) and Solve[eq,var,elim] ( but this one
- did not work too).
- Have any of you encountered a similar problem? Is there a way to obtain "ac" in
- terms of just a, b, c, d, e, f, g&h eliminating the rest. I would appreciate
- your suggestions. Is there any other software package i could use for this
- problem?
- Here is thanking you in advance.
- Sincerely,
- Nikhil...
