Chapter 11, Problem 11S.5P

(a)

To determine

Area required to achieve hot fluid (water) outlet temperature, ${\text{T}}_{\text{m,o}}=330\text{K}$ .

(b)

To determine

Outlet temperatures, ${\text{T}}_{\text{h,o}}$ and ${\text{T}}_{\text{c,o}}$ , as a function of overall coefficient for the range, $\text{200}\le \text{U}\le \text{400}{\text{W/m}}^2\cdot \text{K}$ with surface area A found in part (a) with all other heat transfer conditions remaining the same as for part (a).
