【Abstract】 A new mathematical model is set up in terms of Bernoulli equation and drag property of thepipe and nodal continuity equation,which solve parameters of operation condition for parallel waterservice system of pressure pump pipeline of single node. Two methods have been given,with which theparameters of operation condition can be solved by mathematical and graphical analysis respectively.An example of practical application is given.更多还原
