Pressure-driven flow in a straight duct of circular cross-section with radius R. Inlet and outlet boundaries have
uniform, dissimilar pressure boundary conditions. The mean fluid temperature at the inlet is Tm,i. The pipe is
subjected to a uniform wall heat flux, q'', throughout its length, L.
From the Velocity Field Determine
VXc = centerline axial velocity
VXm = mean axial velocity
Re = Reynolds number
= mass flow rate From the Temperature Field Determine
LE,T = thermal entry length
Tm,o = outlet mean temperature
Tw,o = outlet wall temperature
Tc,o = outlet centerline temperature τw = wall shear stress
