Hello all,
I’m looking for some guidance on a calculation that I’m trying to do. I posted a similar recent thread titled 'Heating of air in enclosure - calculation and experiment discrepancy'. This question is in relation to the same device as the one in that other thread, but the enclosure is...
Hello everybody,
I would like feedback please on a large discrepancy between a theoretical calculation and an experimental measurement I have taken.
I ran a 470 Ohm 5 Watt ceramic (at 50 V and 0.1 A, both confirmed using a multimeter) resistor inside of an 8 litre insulated cooler box and...
Hello,
I try to use equation to calculate how much flow rate needs to be to removed heat from apparatus, but I confuse myself. I thought more flow means more heat taken away?
I take this equation:
Qdot = Vdot * cp * ρ * ΔT.
I rearrange to find Vdot:
Vdot = Qdot / cp * ρ * ΔT
If Qdot kept...
Hello,
New user here, excited to draw on knowledge of others.
I have a small box to contain a science apparatus. The science apparatus needs to be kept cool and has inlet and outlets for fluid tubes. Sorry for this question if it is silly: do I need to cool the inside of the box as well? If I...
