Graduate Thermal Physics: Cooling by both Conduction & Convection
Hi Simon, I was a Veterinary Technology major, and am currently doing Animal Sciences, not physics which would probably explain why I haven't learned about the time constant etc and physics in general since we didn't have any classes for those. This is my first time actually doing thing kind of...- Ying_Thes

Graduate Thermal Physics: Cooling by both Conduction & Convection
Hi Simon, The plot of lnTemp vs time and Temp vs Time are virtually identical, and they both show a slight curve but the lnTemp vs Time plot does fit the straight line slightly better. So if I get the equation for the fitted line in the format of y=mx + c how would I be able to get the Time...- Ying_Thes

Graduate Thermal Physics: Cooling by both Conduction & Convection
I have plotted a graph of log-temperature vs time by transforming the temperature data using LOG10 (data), is this correct for getting the log-temperature? The line mimics that of the temperature vs time plot very closely. If the data does not produce a straight line plot, is there another way...- Ying_Thes

Graduate Thermal Physics: Cooling by both Conduction & Convection
Oh~ Thanks a lot, I tend to take things too literally with mathematical language, kinda explains my grades back then. I will do that the error distribution plot. So if I get y = -0.0156x + 7.4019 do I solve it to get the time constant? Because I read somewhere that m (slope), in this case...- Ying_Thes

Just wondering, what do you mean by straight line? Horizontally straight? -No, it's not, Vertically straight? - No, it's not. But it is a straight downwards slope for the duration of the experiment.- Ying_Thes

Graduate Thermal Physics: Cooling by both Conduction & Convection
As I mentioned in the original post, I calculated heat loss for the bags with this formula Heat loss C/sec/cm2 = {[k * (Ti - Tf)] / As} / t Where k = Thermal conductivity of tree bark or air Ti = initial temperature Tf = final temperature As = Surface area exposed to either tree bark or air t...- Ying_Thes

Graduate Thermal Physics: Cooling by both Conduction & Convection
I was thinking the same in regards that I already established the results, but my supervisors seems to think that the thermal time constant plays a big role and wants me to include a thermal time constant model if possible, is there any references sources you would refer me to for that?- Ying_Thes

Graduate Thermal Physics: Cooling by both Conduction & Convection
Hi Simon, Thanks for replying. From the rate of cooling which I initially calculated it showed that the bags against the tree trunks were cooling faster than the control which was hanging off a branch. This experiment is part of my undergrad honours project and we were just testing the...- Ying_Thes

Getting some guidance for my thesis
Hi everyone, I am new to the forum (as you probably suspect from this post) and I am basically trying to get some guidance with my honours thesis about thermal time constants and comparing cooling rates~- Ying_Thes

Graduate Thermal Physics: Cooling by both Conduction & Convection
Hi all, I am not sure if the is the right place to post the question being new to the forum, but I am looking for some help with a heat transfer experiment that I ran for my honours thesis. Essentially the aim is to determine if warmed saline fluid bags taped to 3 different types of tree barks...- Ying_Thes
