peer agreement (net): +1diversity factor Explanation: Found this reference. Diversity factor: It is the ratio of the sum of the individual maximum demands of the various subdivisions of a system (or part of a system) to the maximum demand of the whole system (or part of the system) under consideration. From: Ocean Energy Modeling and Simulation with Big Data, 2020 If this is not the correct answer, might give you a pointer. |

peer agreement (net): +1coincidence factor Explanation: "coefficient de simultanéité de foisonnement Définition: Quotient de la pointe de la demande globale simultanée par la somme des pointes des demandes individuelles. Note: Le « facteur de diversité » est l'inverse du « coefficient de simultanéité ». coincidence factor Définition The ratio, expressed as a numerical value or as a percentage, of the simultaneous maximum demand of a group of gas appliances or consumers within a specified period, to the sum of their individual maximum demands within the same period. Note: Diversity factor is the reciprocal of the coincidence factor." https://vitrinelinguistique.oqlf.gouv.qc.ca/fiche-gdt/fiche/... "‘The coincidence factor is formally defined as the design flow rate for downstream domestic hot water outlets divided by the sum of maximum flow rates for individual downstream domestic hot water outlets" https://www.designingbuildings.co.uk/wiki/Coincidence_factor Complication (as regards electrical systems anyway): "The coincidence factor is the reciprocal of the diversity factor. The simultaneity factor may be identical to either the coincidence factor or the diversity factor, depending on the sources of definition; the International Electrotechnical Commission defines the coincidence and simultaneity factors identically, with the diversity factor being their reciprocal. Since the only change in definition is to take the inverse, all one needs to know is if the factor is greater than or less than one. [ …] In the heat networks design the coincidence factor is often called a diversity factor (CIBSE guidance, DS 439). So, in the context of hot water systems the diversity factor is always less than 1. For space heating, for more than 40 dwellings the factor levels out to approximately 0.62. For domestic hot water at 40 dwellings it is slightly below 0.1 and keeps decreasing further with additional connections. Diversity The unofficial term diversity, as distinguished from diversity factor, refers to the percent of time available that a machine, piece of equipment, or facility has its maximum or nominal load or demand https://en.wikipedia.org/wiki/Diversity_factor If the IEC definition also holds (water) for water, then 'simultaneity factor' might be a workaround ... However, 'coincidence factor' sounds right for your case where, if I understand things, there are several sources of water supply which, via storage tanks, feed outlets. Not all outlets will be discharging water at the same time, so instantaneous input into the tanks does not need to match the potential maximum output, and the question of 'coincidence' serves to calculate how much water is likely to be removed from the storage capacity over a given time and whether it can be replaced by input into storage before the next drawdown. -------------------------------------------------- Note added at 1 hr (2024-01-04 10:28:42 GMT) -------------------------------------------------- In many contexts, foisonnement is the 'bulking factor'. Usually, as the term suggests, it implies an increase in whatever is being measured, but it can also be a decrease. In your case, foisonnement appears to be a decrease. |

bulking Explanation: Le facteur de foisonnement est un paramètre exprimant le rapport entre le poids et le volume d'un agrégat selon la distribution de ses composants, par exemple. |
