What is the Nusselt number for fully developed laminar flow in the pipe for constant temperature boundary condition?

in Thermodynamics Forum

Ans: Nu = 3.66

Nu = hD/K

where,

h = convection heat transfer coefficient, W/m^2.K [To be calculated]

D = diameter of pipe, m

K = Thermal conductivity of material, W/m.K
