Support can come directly from the vendor, it may come from the vendorâs developer, or potentially a 3rd party. Support can be provided onsite, or it may be online. Itâs important to identify how your ERP support will be delivered, and if it makes sense for you and your staff.
Geologists calculate that, for every mile you dig beneath the Earth's surface, the temperature rises 15 F and the pressure increases simultaneously at a rate of about 7,300 pounds per square inch. Violations of the 15-degrees-per-mile rule are unknown and constitute the notorious forbidden zone.
At depths greater than about 30 feet below the surface, however, the soil temperature remains relatively constant throughout the year, as shown in Figure 3, below. Figure 3. Amplitude of seasonal soil temperature change as a function of depth below ground surface. Vertical closed-loop earth heat exchangers are installed in boreholes 200 to 300 feet deep, where seasonal changes in soil temperature are completely damped out. Well-based open-loop systems also extend to this depth or deeper. These ground loop configurations are thus exposed to a constant year-round temperature.
