    HVAC Attic to Pool Heat Exchange, will car radiator collect heat?

    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...

    I What is the most efficient radiator shape?

    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)

    How exactly does Hawking radiation work?

    Homework Statement 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. Homework Equations none...

    Thermal Management Question in Spacecraft

    Hello guys, 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...

    Black/white radiator vs white/black wall: radiation

    Hi, 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 :)...

    Overall Heat transfer coefficient for a radiator

    Hello all. 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...

    How to design a radiator to dissipate heat generated by a 39 KW rotary engine?

    No separate coolant is used, instead lubricating oil to be used for both lubrication and cooling of engine. How to calculate radiator size, coolant flow rate?
