Using a table, calculate the head loss in psi for a 2,000 ft section of new 10" Cast iron pipe with a flow of 650 GPM:

To calculate the head loss in psi for a section of pipe, it's crucial to use the appropriate formulas and water flow data. In this case, the problem involves a 2,000 ft section of a new 10" cast iron pipe with a flow of 650 GPM.

The head loss due to friction in a pipe can be calculated using the Darcy-Weisbach equation or the Hazen-Williams equation, typically using a table for common materials and diameters to find the equivalent friction loss. For the 10" cast iron pipe, tables will usually provide the head loss per 100 ft of pipe for certain flow rates.

When using the correct data from the table for the flow of 650 GPM, the table may show that the head loss for this flow rate is approximately 2.12 psi for every 100 feet of distance. To find the total head loss for the 2,000-foot length of the pipe, multiply the head loss per 100 feet by the number of hundreds in 2,000 feet (20).

Thus, the total head loss is calculated as follows:

Head loss for 100 ft = 2.12 psi

Total head loss for 2000 ft = 2.
