Question

An uninsulated steam pipe passes through a room in which the air and walls are at 40°C. The outside diameter of the pipe is 80 mm, and its surface temperature

Answer 1

To calculate the rate of heat conduction through the uninsulated steam pipe, use the formula Q = k * A * (ΔT / d), where Q is the rate of heat conduction, k is the thermal conductivity, A is the surface area of the pipe, ΔT is the temperature difference between the pipe and the room, and d is the diameter of the pipe.

Step-by-step explanation:

In order to calculate the rate of heat conduction through the uninsulated steam pipe, we need to use the formula for heat conduction given by:

Q = k * A * (ΔT / d)

where Q is the rate of heat conduction, k is the thermal conductivity, A is the surface area of the pipe, ΔT is the temperature difference between the pipe and the room, and d is the diameter of the pipe.

Given that the outside diameter of the pipe is 80 mm and the surface temperature is at 40°C, we can calculate the rate of heat conduction.
