Incident Energy Analysis. A component of an arc flash hazard analysis used to predict the incident energy of an arc flash risk assessment for a specified set of conditions. An incident energy analysis is an important part of performing the arc flash hazard analysis for a specific task and item of electrical equipment.
Tilling hydrated lime into bare soil effectively raises pH levels. Except for acid-loving plants like camellias (Camellia spp.), which grow in U.S. Department of Agriculture plant hardiness zones 6 through 10, depending on species, garden and lawn soils should have a soil acidity or pH of between 6.0 and 6.5.
For soils above pH 7.5 with free lime, the estimates based on CEC are not valid. The acidifying agent must neutralize all the free lime (carbonates) before soil pH will decrease. It takes a lot of an acidifying agent to neutralize the free lime. One percent free lime in a soil is equal to 20,000 lbs./ac. (one per cent of 2,000,000 lbs.). Soils with free lime often have 5 per cent or more free lime.
