Transcribed Image Text:Superheated steam at 350 °C flows through a pipe whose thermal conductivity is kp = 16 W/m.K. The inner diameter and thickness of the pipe are 26 cm and 1 cm, respectively. The surrounding temperature is 28 °C. The convective heat transfer coefficient at the steam side and the outside of the pipe is 90 W/m?.K and 15 W/m?.K, respectively. Derive an expression for the temperature profile across the %3D pipe thickness as a function of the radial position r. T = 28 °C, h, = 15 W/m?.K Ts = 350 °C h; = 90 W/m?.K ri %3D r2 Cross-sectional view of the pipe

Expert Solution

Step 1

Boundary Conditions

T( r₁) = T₁ =350^oC

T( r₂) = T₂ = 28^oC

$\frac{d T}{d r} = \frac{C_{1}}{r}$

T(r) = C₁ lnr + C₂

T( r₁ ) = C₁ lnr₁ + C₂

T( r₂ ) = C₁ lnr₂ + C₂
