Logarithmic mean temperature difference information

In thermal engineering, the logarithmic mean temperature difference (LMTD) is used to determine the temperature driving force for heat transfer in flow...

In mathematics, the logarithmic mean is a function of two non-negative numbers which is equal to their difference divided by the logarithm of their quotient...

surface area (m2) Δ T L M {\displaystyle \Delta T_{LM}} = logarithmic mean temperature difference (K). The overall heat transfer coefficient takes into account...

computer memory needed to store that value. Differences in order of magnitude can be measured on a base-10 logarithmic scale in "decades" (i.e., factors of ten)...

historically denotes "potential of hydrogen" (or "power of hydrogen"). It is a logarithmic scale used to specify the acidity or basicity of aqueous solutions. Acidic...

expresses the ratio of two values of a power or root-power quantity on a logarithmic scale. Two signals whose levels differ by one decibel have a power ratio...

whenever "caloric" (what is now known as heat) falls through a temperature difference, work or motive power can be produced from the actions of its fall...

occurs only irreversibly, driven by a finite difference between the system temperature (T) and the temperature of the surroundings (Tsurr). The equality...

More generally, the dimensionless heat capacity relates the logarithmic increase in temperature to the increase in the dimensionless entropy per particle...

exceeds the mean free path of the electrons, resulting in many collisions between them on the way through the channel. The only practical difference between...

{u_{*}}{k}}\ln {\frac {z}{z_{o}}}} . So, we see that the mean flow in the surface layer has a logarithmic relationship with depth. In non-neutral conditions...

Both the apparent and absolute magnitude scales are logarithmic units: one whole number difference in magnitude is equal to a brightness variation of about...

historical system. The scale is reverse logarithmic: the brighter an object is, the lower its magnitude number. A difference of 1.0 in magnitude corresponds to...
