Question: Boundary Value Problem

I am tried to solve the following problem. here is the code and boundary conditions as well as parameters used in the problem. Please help me to get the numerical solution and getting plots between Cu and eta as well as D(f)(eta) vs eta.

Please help me to get the graph of CU v/s eta also D(f)(eta) vs eta
