Sorry to bug you again sir, in the equation of Newton's law of cooling. Can i use the K for my material? if so, what unit should i be following. Assuming I have my temperatures as Celsius and my time as minutes. What would be the unit I would use for K?

Update: i guess about now i seem to have found Newtons law of cooling as a guide to answer my question as what chester said and i will try to mix it up with the link i posted above. Hopefully i can finish it within tomorrow if i would have spare time. Once again i'd like to thank mr chester...

Oh ok. Thanks. I'll try your experiment and observe a little later but as of now ill try sir chester's guide also about Newton's cooling law

Thanks for the reply :) Yes I will still do that kind of testing at certain time where i would put a thermometer or data logger in the container to see how long will the temperature last. But I would like to know the estimated time on how long it could last with computation :) I would like to...

I think i did my calculations wrong again T_T Below is the snap of my calculation. Another thing sir, i seem to have found a new reference, can you verify it if you have the time if this relates to my problem :) http://www.fao.org/docrep/006/y5013e/y5013e0a.htm

Thanks again for replying to me sir, though I am sorry for the late reply. I would like to ask this about Newton's law of cooling. Does the equation factor the thermal conductivity of the material and its thickness or do i neglect it? sorry again for this simple question as i don't have any...

Thanks for the reply sir chestermiller :) now i got my initial equilibrium temperature, it is also illustrated below. t1 = ice temperature = 0 Celsius t3 = outside temperature or room temperature = 32 Celsius d1 = inner diameter of the container = 8 inches d2 = outside diameter of the...

Could you link me to that. :) I am really quite slow on this topic. :(

Oh :( would there be a way just to focus on the container? Neglecting all other factors.

Thanks for the reply. As of now I'm still reviewing my past lessons about heat transfer. I seem to be on conduction thru a cylindrical wall. With this topic i can calculate the heat transfer thru the differential thickness with its unit as btu/hr or kj/hr. Btw, i assume my calculations as...

Good day to all, Hi, i would like to ask if there is a way to calculate the temperature change at a given time. I will use this as a basis for my study which is about designing an ice container and i would like to know how long does my ice last given its own temperature and the outside...

Hi! I am derek from the Philippines. Still an undergrad though! :)
