temperature increased does not match the heat flux
 
I'm using FLUENT simulating a 3d model on conjugate heat transfer in a square duct. Water goes through a square duct(a laminar flow) and the duct is given a uniform heat flux. after the residuals and the parameters converged. the Area-Weighted Average temperature outlet is greater than than expected (about twice) the expected temperature is calculated as followed : (delta)t=Q/(M*Cp) FLUENT reported t=2*(delta)t can anyone help thans in advance
