1. The problem statement:

(a)Concider a stainless steel hollow pipe containing a saturated steam and has length L, cooled by convection & radiation. Find formula for T2.

(b) Another question "Not related to the previous one": How would I know if a gas has gone turbulent?

2. Homework Equations :

For (a): Q = 2 Pai K (T1 - T2) / ln (r2 / r1)

For (b): Re = e u l / M ??

3. The Attempt at a Solution :

(a) Do I ignore the saturated steam, and re-write the equation (a) with respect to T2 only??

Thank you!
