WebThe thermal analysis of an underground power conduit for electrical cables is essential to determine their current capacity with an increasing number of demands for highvoltage underground cables. The temperature rises around a buried cable, caused by excessive heat dissipation, may increase considerably the thermal resistance of the cables, leading … WebTo calculate churn rate, begin with the number of customers at the beginning of August (10,000). In this example, you lose 500 (5%) of these customers, but acquire 5,000 new …
