    Gleaning More Data From Newton's Law of Cooling

    IRSTUFF, Thanks for your help. So, I am assuming that we are incapable of empirically determining the value of this exponential value as a function of input power? Thanks, Tei

    Gleaning More Data From Newton's Law of Cooling

    IRSTUFF, Thanks for your response. Based upon the equations that I have listed, it seems like all the unknown constants can be lumped together as they are the only things staying the same between power levels. I'm just wondering how I can group them all together and come up with a method of...

    Gleaning More Data From Newton's Law of Cooling

    Hi James, Thanks for the response. I am indeed finding a solution to my data which looks very similar to this graph: The statistical tool that I am using has determined that my value of k (as shown in the picture) is 5.66E-5 (s^-1). However, this data was determined empirically using a fixed...

    Gleaning More Data From Newton's Law of Cooling

    Hi, I am currently trying to expand upon the data set that I recently recorded from a heat exchanger that I am trying to better understand. I'd like to use Newton's law of cooling (the differential version) to try and find a way of determining the time it will take for the cold side of my heat...

    Necessary Compression Force

    Thank you very much. I will begin to start reading them!

    Necessary Compression Force

    HI Stefano, Would there be an equation that I could use to calculate this permanent height difference (even with buckling)? Thanks, Tei

    Necessary Compression Force

    Hi, Thanks for the reply. I am attaching a diagram for you to reference. The force is perpendicular to the top plane of the "dish". Thanks, Tei http://files.engineering.com/getfile.aspx?folder=4064bdd0-0632-4fec-8172-f5735b60928c&file=Diagram.jpg

    Necessary Compression Force

    Hi, This seems to be a deceptively simple question, but I am trying to calculate the change in height of an aluminum "dish" with a "lip" that is .10mm tall with an OD of 15.50mm and an ID of 15.00mm. It is made from a .50mm disc with OD of 15mm, so the base is .40mm thick. I have calculated...
