Logarithmic temperature
WitrynaA logarithmic scale (or log scale) is a way of displaying numerical data over a very wide range of values in a compact way. As opposed to a linear number line in which every unit of distance corresponds to adding by the same amount, on a logarithmic scale, every unit of length corresponds to multiplying the previous value by the same amount. WitrynaThe Logarithmic mean temperature difference formula is defined as the log of the mean difference of the temperature values is calculated using Logarithmic mean temperature difference = Heat exchanged /(Correction Factor * Overall Heat Transfer Coefficient * Area).To calculate Logarithmic mean temperature difference, you need …
