Model for torque estimation of pump system with horizontal pipe network

This paper investigates the possibility of torque estimation of Centrifugal Pump System (CPS) with horizontal pipe network topology. It illustrates the concept of a model-based scheme for hydraulic system simulation. The simulation model developed for CPS takes into consideration the hydraulic&#x...
