Dear Sir, Madam,

I hope you are doing well..

At first let me introduce myself.. I am Mudhar an international Ph.D student in the University of Bradford, United Kingdom working in modeling of reverse osmosis units for wastewater treatment. Actually I have stacked with a solution of second order differential equation. Unfortunately I couldn't find a way to solve this problem ... please. AS expected, In case if I can solve this equation this might guide me to construct my new model.

My equation has two variables in the right side of equation as mentioned below please

d2F(x) / dx2 ) = alpha * F(x)) / [ (Beta - (gama * C(x)) ]

where alpha , beta , gama are constants but F(x) and C(x) are variable with x dimension I have boundary conditions for this equation as

at x =0, F(x) = F(inlet), C(x) = C(inlet) at x = L , F(x) = F(outlet) , C(x) = C(outlet)

Please do me a fevour and have a look at my attachment and you definitely will let me know if there is a possible solution or not.

I will be waiting for your response even if takes a long time

Accept my apologize for inconvenience

Warm regards

Mudhar
