boundary condition in double pipe heat exchanger

I have been trying to simulate a double pipe heat exchanger using ansys CFX15.
in defining boundary condition, mass flow rate applies for both hot and cold inlet ,in this case results shows accurate values of outlet temperatures but shows incorrect results for surface heat transfer coeff.
On the other side, when velocity was applied for both inlets results shows accurate values of inner and outer surface heat transfer coeff but this time outlet temperatures shows incorrect value.
plizz help me i really confused ,
