Homework Statement
every where we require at least 3 variables out of 4(l,d,q,hf)l=length,d=diameter,q=flow rate, hf=head loss due to friction. assume water and e=0.02(roughnss coeff)
what shall happen if 2 of them are known and remaining 2 unknown
ex.known=l,d; unknown=hf,q;
we also know the height of tank...H now i am unable to understand how do i solve it.

NOTE-- we know onlyLength and dia of pipe and properties of fluid and pipe.
Homework Equations
How do we solve and get hf and q at same time.
The Attempt at a Solution
i have tried about 100 methods including iteration by assuming q,hf f etc etc at each try, but i am never able to get any near to correct solution.
I have written programs in C for the purpose. I have posted image of system i need to solve, please help.I have even tried hazen williams equation but i want to get the answer with Darcy equation... please help
