    Flow Matlab
In summary, the conversation is about constructing a MATLAB file and understanding the equations involved in applying nodal analysis. The person asks for help and receives a helpful response with explanations and clarifications. They also mention using "fsolve" and question how to find the values of C1 and C10 without knowing the values of L1 and L10.

WOW what a valuable POST THANX!


Regarding the Q's:

Q1=Q2+Q3
Q3=Q4+Q5
Q5=Q6+Q7
Q1=Q10
Q3=Q9
Q5=Q8

This is more like applying Nodal analysis ; reminds me of Current in = Current out. Which i understand.

Those three i still don't get :

Q1=Q10
Q3=Q9
Q5=Q8


Also Regarding the dp_all i don't get.

I can also see you have wrote dp2 twice;
->dp2=C2*Q2^2
->dp2=dp3+dp4+dp9
Similarly for dp 4

while you said dp6=dp7.

Can you please provide me with a litlle bit more details so it breaks down to pieces.

May you also what C represents ?

And The last four lines specifically :-

dp_all=dp1+dp2+dp3
dp2=dp3+dp4+dp9
dp4=dp5+dp6+dp8
dp6=dp7

I don't understand them. I tried applying the nodal anaylsis but it seems not to work how did you work those equations out ?

Anyone please help me submission is tommrow
 
  • #6
OK i understand all the equations now but when i find the values of C1 & C10 i won't be able to because i don't have the values of L1 & L 10 although L1 = L10 shall i assue a value ?


How can i use "fsolve"
 

1. What is Matlab and how is it used in flow computation?
