To calculate the load factor, what should you do with the bank volume and swell percentage?

The load factor calculation is essential in construction and excavation projects to determine the efficiency of material handling. When calculating the load factor, the formula typically involves understanding how the swell percentage affects the bank volume.

In this context, bank volume refers to the original volume of material before any expansion (swell) occurs when it is excavated. The swell percentage indicates how much the volume of the material will increase once it is disturbed and becomes loose.

To find the load factor, it's important to recognize that the swell percentage represents an increase over the bank volume. By dividing the bank volume by the total volume after swell, which combines the bank volume and the increase from the swell percentage, you effectively assess how much more volume there is due to that swelling. This formula provides a measurement that can be used to quantify the efficiency of the excavation and loading processes, as it reflects the relationship between the raw material available and its expanded state.

Thus, the correct method involves dividing the bank volume by the sum of the bank volume and the swell percentage, allowing for a comprehensive understanding of load dynamics in construction practices.
