    Flow Matlab
AI Thread Summary
The discussion revolves around constructing a MATLAB file for a project involving nodal analysis and fluid dynamics equations. The user seeks assistance with specific equations related to flow rates (Q) and pressure drops (dp), expressing confusion particularly about the relationships Q1=Q10, Q3=Q9, and Q5=Q8, as well as the variable C, which represents a coefficient in the equations. The user also mentions issues with the dp equations, specifically dp2 and dp4, and how they relate to each other. There is a request for clarification on how to apply nodal analysis effectively, especially in calculating values for C1 and C10 without known values for L1 and L10. The user is looking for guidance on using MATLAB's "fsolve" function to solve these equations, emphasizing the urgency of the project submission deadline.

Anyone please ? I have to submit this in 2 days please help...
 
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
 
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"
