A remote sensing technique that monitors the electrical resistance of soils in a restricted volume near the surface of an archaeological site; buried walls or features can be detected by changes in the amount of resistance registered by the resistivity meter.
A Simplified System of Defining Fluid Resistance. Over the years, The Lee Company has developed the Lohm system for defining and measuring resistance to fluid flow. Just as the ohm defines electrical resistance, the Lohm or liquid ohm can be used as a measure of fluid resistance. The Lohm is defined such that 1 Lohm will flow 100 gallons per minute of water with a pressure drop of 25 psi at a temperature of 80Â°F.
