You are the engineer responsible for the utilities plant of your company. You hear from the operators that there are problems transporting steam from the boiler to a jacket, where the steam is used to heat up a reactor. Apparently, there is a lot of steam condensing along the pipes, so there are serious issues for the reactor to reach the desired temperature.
After inspecting the site and talking to the operators, you see the pipe is exposed to air, and they tell you that this is a “4-in Schedule 40”. You are also attentive to the fact that this winter, temperatures have been lower than usual.
You are asked to propose one or more solutions to this problem. As part of your work, you should:
1. Do a quantitative analysis of the current situation, attempting to explain why the condensation is taking place. You may need to look up values for convection coefficients, and make any necessary assumptions – just make sure to state them clearly.
2. Do a quantitative analysis of one solution you propose – clearly describe any materials you propose to use, specifications, and dimensions.
