I realized I calculated my temperature difference from both extremes, instead of from a mid point to either extreme. My new DeltaT will be plus/minus50°C. Because of this I will only use one piece of 1/4" plywood (same thickness as before), and same dimensions. Heat loss through one wall will...

See, this is why I asked :smile: Thanks for pointing out those errors. So I misunderstood the calculation of my overall conductance (U), or the overall HTC. Breaking things down, it should be UAir=\frac{1}{k Air} UPlywood=\frac{dX Plywood}{k Plywood} UABS=\frac{dX ABS}{k ABS} Then I can...

[FONT="Arial"]Hey all! I am thinking of building a box in which the insides can be held a constant temperature. I would like to see if I can determine some parameters for the box. My first step is to determine heat loss through the box. I'm estimating that the largest difference in heat...

Thanks for that reply alxm, helped quite a bit. Some follow up questions/comments. 1) The water being boiled is standing so there is no flow (assuming the flow you are talking about is because of my second question on the counterflow heat exchanger). I didn't think it'd be as easy as finding...

First let me apologize for any spelling mistakes as I am on a mobile device. Second I do have a few questions regarding thermodynamics for a project I would like to begin. 1) is there a way to calculate a volume of water in either the amount of time and the amount of energy required to make...
