EPANET's computational engine is available for download as a separate dynamic link library for incorporation into other applications. [7] The source code for EPANET 2 is available on the EPA's EPANET website. [8] In 2012, Baseform released a rewrite of the EPANET toolkit in Java under the GNU GPLv3 license. [9]
Given a starting node, we work our way around the loop in a clockwise fashion, as illustrated by Loop 1. We add up the head losses according to the Darcy–Weisbach equation for each pipe if Q is in the same direction as our loop like Q1, and subtract the head loss if the flow is in the reverse direction, like Q4.
The base load [2] (also baseload) is the minimum level of demand on an electrical grid over a span of time, for example, one week. This demand can be met by unvarying power plants [ 3 ] or dispatchable generation , [ 4 ] depending on which approach has the best mix of cost, availability and reliability in any particular market.
The base stock model is a statistical model in inventory theory. [1] In this model inventory is refilled one unit at a time and demand is random . If there is only one replenishment, then the problem can be solved with the newsvendor model .
Unit prefixes are common base-10 or base-2 powers multiples and submultiples of units. While a base unit is one that has been explicitly so designated, [2] a derived unit is unit for a derived quantity, involving the combination of quantities with different units; [1] several SI derived units are specially named.
Since electrical energy is a form of energy that cannot be effectively stored in bulk, it must be generated, distributed, and consumed immediately. When the load on a system approaches the maximum generating capacity, network operators must either find additional supplies of energy or find ways to curtail the load, hence load management.
Normality can be used for acid-base titrations. For example, sulfuric acid (H 2 SO 4) is a diprotic acid. Since only 0.5 mol of H 2 SO 4 are needed to neutralize 1 mol of OH −, the equivalence factor is: f eq (H 2 SO 4) = 0.5. If the concentration of a sulfuric acid solution is c(H 2 SO 4) = 1 mol/L, then its normality is 2 N. It can also be ...
In economics, a unit demand agent is an agent who wants to buy a single item, which may be of one of different types. A typical example is a buyer who needs a new car. There are many different types of cars, but usually a buyer will choose only one of them, based on the quality and the
