Velocity and temperature profiles for laminar flow in a tube of radius ro = 10 mm have

Question:

Velocity and temperature profiles for laminar flow in a tube of radius ro = 10 mm have the form u (r) = 0.1 [1 – (r/r_o)²] T(r) = 344.8 + 75.0(r/r_o)2 – 18.8(r/r_o)⁴ with units of m/s and K. respectively. Determine the corresponding value of the mean (or bulk) temperature, T∞ at this axial position.
