My attic gets very hot even with the exhaust fan I installed. I would like to move than heat to my swimming pool. I currently have a FAFCO solar pool heater where the pool pump pumps water up onto my roof and thru the 12' long solar panel and down back into the pool. I would like to free up roof...
What is the highest efficiency (electromagnetic) radiator shape? Meaning, a shape with the highest radiated power/volume (radiated power is in this case dependent only on surface area and how much of the radiation is reabsorbed by the radiatior)
For school I'm doing a project on hawking radiaton but I have very big difficulties trying to understand it.
I'm trying to understand the matter about: Unruh effect, particle pair (antimatter - matter) and the theory of relativity regarding vaccuum.
The following data refer to an electrically operated refrigerator:
- Efficiency : ## \xi = 2.4##
- Temperature inside: ##T_i = -9 ° C ##
- Temperature of the radiator ## T_r = 40 °C ##
- Room temperature: ## T_s = 35 °C##
- Total surface of walls: ## A = 3.2 m ^ 2 ##
Below I am presenting a question related to thermal management in spacecraft. Perhaps many of you might find it interesting! And this could be a real-life problem for thermal engineering in a spacecraft. So, the question is following:
An instrument dissipates 10W and, in order for...
Situation A: Black radiator in a room with white walls.
Situation B: White radiator in a room with black walls.
Which one is the most efficient situation?
I know that convection is dominant if you look at a radiator, but i would like to know the answer in terms of radiation.
Thank you :)...
I need to design a radiator for 43kw heat dissipation. I have used the LMTD method for finding out the contact surface area of the radiator. But I have a small problem. I cannot find the area unless i know the overall heat transfer coefficient. Can somebody please give an estimate of...
