Question

Problem-2 (5/20) Steam at 200 C flows in a 5 cm bare pipe which is 2 mm thick. Calculate the annual heat loss from the pipe if the convective heat transfer over the pipe is 100 W/m$^2$C and the average ambient temperature is 10 C. If the surface is insulated with 2.5 cm thick glass wool, calculate the annual heat loss. In the insulated case, the convective heat transfer coefficient decreases to 25 W/m$^2$C. Steam flows in pipe around the year. State your assumptions.

Step 1

First, we need to calculate the surface area of the bare pipe. The surface area can be calculated using the formula: Surface area = 2 * π * r * L where r is the radius of the pipe and L is the length of the pipe. Given that the pipe is 5 cm in diameter, the Show more…

Problem-2(5/20) Steam at 200Â°C flows in a 5 cm bare pipe which is 2 mm thick. Calculate the annual heat loss from the pipe if the convective heat transfer over the pipe is 100 W/mÂ°C and the average ambient temperature is 10Â°C. If the surface is insulated with 2.5 cm thick glass wool, calculate the annual heat loss. In the insulated case, the convective heat transfer coefficient decreases to 25 W/mÂ°C. Steam flows in the pipe throughout the year. State your assumptions.
