![]() ![]() ![]() mol-1 for which 83 kJ mol-1 can be set in (5).Haynes (7) has derived an equation based on the Arrhenius equation to calculate the T mkt, the mean kinetic temperature: Tmkt E/R-ln e-E/RT1 + e-E/RT2 + e-E/RTn n E: activation energy in kJ Several times over the past week, the temperature spiked to around 50F. mean kinetic temperature should be calculated instead of the arithmetic mean temperature. What is the appropriate length of time to use when calculating MKT? For example, we have a refrigeration unit in which we store products that need to be kept at a temperature range of 35-45F. Calculation-of-Mean-Kinetic-Temperature-MKT-in-Excel-Rev3 Posted on Maby Vacker No Comments Calculation-of-Mean-Kinetic-Temperature-MKT-in-Excel-Rev3 This is the excel sheet for automatic calculation of Mean Kinetic Value (MKT) for temperature sensitive goods such as medicines, vaccines etc. Steve I just posted a reply and it has gone the same thing happened the other day, so maybe 2 will turn up (like buses) Wow, thats great Steve If I understand what you have said above would it be more meaningful to add transit times to my waypoints, for example collection at origin to export gateway 5 hours at 20 degress, Flight to import gateway 12 hours at (a guess because I cannot find any cabin temperature at the moment) 25 degress, 5 hours to clear and deliver at say 25 degrees and the product (which has internal temperature controls) at say 5 degrees. You need to enter times for each period to calculate the MKT, otherwise you are indicating that it just spent 48 hours at one temperature and then you don't need the to average at all. Calculation of kinetic parameters from DTA curves using the characteristic temperature Thermochim Acta, 255 ( 1995 ), pp. ![]() I put the numbers from your workbook example, but it only lists the time at origin (48 hours) so the MKT is the origin temp. ![]()
