A tube with 2-cm inner diameter and 1.0-m length, has a uniform wall temperature. Water at 300 K, with fully developed velocity, enters the tube with a mean velocity of 0.05 m/s. The mean water exit temperature is 350 K.

(a) Find the surface temperature by using a thermally developed flow correlation.

(b) If the boundary condition was constant heat flux, what would be the required heat flux?

(c) For part (b), calculate the heat transfer coefficient and wall temperature at the middle of the tube.
