The following thermodynamic properties will be calculated:ĭensity, dynamic viscosity, kinematic viscosity, specific enthalpy, specific entropy, specific isobar heat capacity cp, thermic conductivity, coefficient of thermal expansion, heat conductance, thermal diffusivity, Prandtl-number, coefficient of compressibility Z, speed of sound.Ĭalculation of Ammonia : if you found an error, please mail to: No garanty for correctness. Lower limit for calculation: -75 C, 0.08 bar bar upper limit: 130 C, 108 bar. For example if I asked you to predict the outcome of a regular fair coin, you have a 50 50 chance of being correct. The higher the entropy the more unpredictable the outcome is. This online chemical calculator may be used to calculate the entropy change of an ideal gas in constant temperature. If only one of a given atom is desired, you may omit the number after the element symbol. Essentially how uncertain are we of the value drawn from some distribution. Enter a sequence of element symbols followed by numbers to specify the amounts of desired elements (e.g., C6H6).

If qk is not None, then compute the Kullback-Leibler divergence S sum(pk log(pk / qk), axisaxis). Recent Saturation Properties (max 20) - download - clear Pressure. If only probabilities pk are given, the entropy is calculated as S -sum(pk log(pk), axisaxis).

Feel free to suggest any changes or point out any mistakes in the code. Entropy is a measure of expected surprise. entropy (pk, qk None, base None, axis 0) source ¶ Calculate the entropy of a distribution for given probability values. Shannons theorem also implies that no lossless. It was created as an assignment for the Information Theory class of Ionian University Informatics Department. The calculation of the sum of probability-weighted log probabilities measures and captures this effect. Lower limit for calculation: -50 C, 1 bar upper limit: 300 C, 500 barĬalculation of thermodynamic state variables of ammonia on the boiling curve This is a very simple script that can calculate the entropy of any given string.
