SUMMARY

The discussion centers on determining the appropriate flow rate value for junction CA in the Hardy Cross method during the second trial of the first loop. The participants debate whether to use the corrected value of -15.3 from the second loop or the corrected value of 22.7 from the first loop. The consensus leans towards using the value of 22.7 from the first loop, as it reflects the most accurate flow rate prior to the second iteration.

PREREQUISITES
  • Understanding of the Hardy Cross method for flow analysis
  • Familiarity with hydraulic network modeling
  • Knowledge of flow rate calculations and corrections

Homework Statement


i have a netwrok of pipe as shown in the figure . I'm asked to find the flow rate using HARDY CROSS method . in the second trial of first loop at junction CA , which value should i use ? -15.3 from the corrected in second loop ? or 22.7 from the corrected value in the first loop ?
