Methods of calculation. Rather than using a theoretical approach to determine short-circuit currents, published standards offer methods to compute a symmetrical steady state solution to which you can apply a multiplier in order to obtain the peak value of an asymmetrical current.

The designer should verify that the design complies with NRCS standards and that the standard applies to the site. The designer must understand the assumptions and calculations contained in the spreadsheets and is responsible for their use. Most if not all spreadsheets contain macros. Many engineering spreadsheets are available for use.

This appendix presents design examples of the retrofitting techniques for elevation, dry floodproofing, wet . floodproofing, and construction of a floodwall in a residential setting. Examples C1 through C5 are a set of examples that illustrate the elevation of a single-story home with a crawlspace. Example C6 ...

In lighting design, the lumen method, (also called zonal cavity method), is a simplified method to calculate the light level in a room.The method is a series of calculations that uses horizontal illuminance criteria to establish a uniform luminaire layout in a space. In its simplest form, the lumen method is merely the total number of lumens available in a room divided by the area of the room.
