A Fixture Unit is not a flow rate unit but a design factor based on the rate of discharge, time of operation and frequency of use of a fixture. to the level of demand created by one single-family dwelling unit. Calculation of battery pack capacity, c-rate, run-time, charge and discharge current Battery calculator. A four-unit residential attached building is a total of 3.22 ERCs. Population equivalent or unit per capita loading, (PE), in waste-water treatment is the number expressing the ratio of the sum of the pollution load produced during 24 hours by industrial facilities and services to the individual pollution load in household sewage produced by one person in the same time. Katherine M. Adler A.T. Total equivalent units for a cost component = A + B × C This section applies to a dwelling unit having the total connected load served by a single 120/240-volt or 208Y/120-volt set of 3-wire service or feeder conductors with an ampacity of 100 or greater.

As an example, a single family detached home is 1 ERC. Dwelling units have special requirements for load calculations. Equivalent Residential Unit Factors. Follow these rules: Use the demand factors of Table 220.84, based on the number of dwelling units. The population equivalent figure also needs to be quoted in conjunction with the required effluent standard when selecting the effluent treatment plant. Thus, one Equivalent Residential Unit (or ERU) is 3,609 square feet of runoff area. PURPOSE. • Residential Areas : Table 3-1 ... population equivalent (PE) Population equivalent (in waste-water monitoring and treatment) refers to the amount of oxygen—demanding substances whose oxygen consumption during biodegradation equals the average oxygen demand of the waste water produced by one person.
