The operating pressure inside water distribution system pipeline depends on the inlet and outlet values of pressure of water. It depends also on the length of pipe line and the pressure drop caused by several factors. So, to maximize the water flow we must maximize the inlet pressure and reduce the factors of pressure drop. For me, i make several balances for avoiding the water flowing stop.
thank you for your response, could you please give me some examples. Typically inside a oil or gas pipeline pressure is high (for example 5-10 MPa in many cases or abve) but for a water pipeline operating pressure much below, so I would like to see some practical examples. thank you again
