Effective design optimisation and selection of pump for supercritical thermal power project

The power requirement of a centrifugal pump for distributing service and potable water increases with pipe size due to higher friction losses and flow resistance. Larger pipes reduce friction but require more power for pumping, but less than the smaller pipe size, while smaller pipes increase friction, necessitating higher power to maintain flow rates. The research includes service water for ship usage and toilet flushing, and potable water for domestic use in the jetty and Coastal Regulation Zone (CRZ) areas. Service and potable water are supplied by the administration to a 300 KL underground tank, with HDPE tanks on building terraces for storage. The key issue is how varying pipe sizes influence power requirements for centrifugal pumps. The challenge is to balance power consumption with effective water distribution, given the coastal location and the specific use cases for service and potable water. The objective is to compare power requirements for different pipe sizes and configurations, aiming to optimise the selection process for centrifugal pumps to ensure efficient water distribution. The analysis involves comparing actual pump configurations with alternate pipe sizes and assessing power consumption and pressure drops for various scenarios.
