I'm working on low budget small solar power project.
I want to transport heat (peak heat power about 1kW) over ~10 meter (~30ft) long pipe or hose.
I was thinking about thin hose (6-8mm / about 1/4 inch inner diameter ) to keep small surface area and make water flow faster (and loose less energy) - im right?
Im thinking about some kind of synthetic, transparent hose. I dont know how this material is called in english, it's similar to fuel hoses used in old motocycles.
I want to cover pipe/hose with some kind of thermal insulation (maybe mineral wool) and maybe aluminium foil to keep/reflect IR radiation inside - it's good idea?
1. I need help to decide what pipe/hose diameter shall I use.
2. Any suggestions about "im right" and "it's good idea" questions above?
I don't need exact formulas, just want to know what is proportional to what etc.
