Conventional Spring-Operated Reliefs in Vapor or Gas Service

The discharge coefficient Cc is not specified. However, for a conservative estimate a value of 0.61 is used. [Pg.389]

The quantity of material relieved is the total flow of water so gv = 200 gpm. [Pg.389]

The backpressure correction is not required because this is not a balanced-bellows spring relief. Thus Kb = 1.0. [Pg.389]

These numbers are substituted directly into Equation 9-4 [Pg.389]

As expected, the relief vent area decreases as the overpressure increases. [Pg.389]
