can I use static enthalpy gradient to describe dT
 
Hi, In a pipe fluid flow, fully developed. After I get the temperature field and velocity field (T, U),How can I get the corresponding temperature gradient in x,r direcion, for velocity, it seems I can use the velocity gradient in x,y,z direction. But there is no temperature gradient in the CFX-post. Cause we can easily get the static enthalpy gradient, can I use the the static enthalpy gradient to describe the temperature gradient, h=Cp*T -->dh/dx=Cp*dT/dx??

Thanks
