In a closed-loop water distribution network, what fundamental law states that the algebraic sum of head losses around any closed loop must equal zero?

The fundamental law stating that the algebraic sum of head losses around any closed loop in a closed-loop water distribution network must equal zero is the principle of conservation of energy. This principle, when applied to fluid flow, dictates that energy cannot be created or destroyed, only transformed or transferred. In a fluid system, this means that the total energy of the water at any given point, represented by its total head, must be consistent throughout the system. A closed loop refers to any continuous path of pipes within the network that begins and ends at the same physical point. Imagine tracing a route through the pipe system wh....
