Hello dears

I have a 2-D pipe flow with the following characteristics :

A fluid enters a pipe of radius 0.06 meters at a constant velocity of 0.1 m/s. The fluid has a density of 1.2 kg/m^3, a thermal conductivity of 0.02 W/mK, a specific heat of 1000 J/kgK, and a viscosity of 1.8e-5 kg/ms. The first 5.76 meters of the pipe are isothermal, held at 300 K. The remaining 2.88 meters of the pipe have a constant heat flux of 37.5 W/m^2 added at the wall

I don't know how to get the Nusselt number along the heated section of the pipe in Fluent. who can tell me what shall I do ?
