A horizontal steel pipe with 2 in outside diameter has an outside surface temper

Question

A horizontal steel pipe with 2 in outside diameter has an outside surface temperature of 150. Calculate the heat losses per m length of pipe, taking into account convection and radiation losses. Assume that the emissivity of the surface of the tube is 0.75, the pipe is exposed to a room temperature of 20, and the convective heat transfer coefficient is 15 W/. The pipe is considered a small grey body in a large enclosure. The temperature of the surfaces seen by the pipe is equal to the air temperature.

Explanation / Answer

this is the equation for heat loss

for calculating area of the pipe

Cross-sectional Area of the Pipe Material:

A = pi*((outer radius) ^2

after calculating area substitute temperature values and emissivity and stefen boltzman constant value

through this we will get heat osss through horizontal steel pipe

= 5.670367(13)×108 W m2 K4.

A=3.14m^2

by substituting these values we will get heat loss
