Heat Transfer Process in Vessel
Hi all,
Let's get straight to the point. I need help regarding heat transfer in vessel. I have a vessel exposed to the surrounding. The liquid temperature (the liquid comes from pipe) in the vessel is lower than the ambient/surrounding temperature. I have been searching, but I couldn't find any example of heat gain by ambient/surrounding temperature on the vessel, there is only always heat loss against ambient temperature.
1. My thought is, based on heat transfer fundamental, temperature will go from high to lower temperature. So, in my case, the temperature vessel should increase, am I right?
2. Maybe, I'm mistaken about surrounding and ambient, is there any difference of them? What is sky temperature? Because I also think if this case involving solar radiation.
3. I have been thinking, this case is just only natural convection, but then my surface temperature is lower than ambient temperature whereas usual in natural convection case the ambient temperature is always lower than ambient temperature
4. The last thought that I have is, is this forced convection by considering wind speed of the surrounding?
Please help me figuring out this confusion. I need to know heat transfer process occur in this case.
Thanks for any help!!
