Abstract:

In this paper, the ventilation network solutions, ScottHinsley method and NewtonRaphson method, are analyzed. The limit of ScottHinsley method is presented, and improved solution is proposed. The comparison and contrast between the two mentioned method shows that NewRaphson method is superior to ScottHinsley method in terms of complex multifan system ventilation network solution.
