I am trying to calculate the radiant heat from the sun into a potable water piping network so I can size a heat exchanger to keep it cool enough not to scald people. It is a circulating system, I have a flow rate of the circulation. Ideally I would like to find a duty per 100 feet of pipe or something similar.

The pipes are carbon steel and insulated. Any ideas on how I would go about this? Can I disregard the radiant heat because of the insulation and just go with the air temperature? I can handle air temperature heat exchange, it's just the radiant heat that is puzzling me.

Thanks

boginator,

Your question relates to a pipe but the same principles can be applied for solar radiation absorption for the cylindrical portion of a tank to a pipe.

For discussion on heat-up due to solar radiation for a tank refer the link below:

Thanks Ankur. That's exactly what I was looking for.
