【Example】
Under the following conditions, the appropriate nominal size would be determined as
described below. Inlet pressure(P
(W): 400kg/h. First, find the point[A] where (P
[B] where a line drawn straight down from point[A] intersects the (W) line. In the
above example, the point[B] is located between the 15A and 20A nominal size valves,
so larger size of 20A should be selected.
