i RELIEF VALVE DISCHARGE CALCULATION D-400 REACTOR 6:15 P. M. - JANUARY 19, 1980 FROM: Farris Relief Valve Catolog No. FE336, Page 3.3 24.3 Vj.25 (P1-P2) " Kp Kg Ku Where: A = Orifice Area (In.2), Q Orifice = 11.05 In.2 = Liquid capacity in l.S. gallons per minute. Pi = Set pressure at inlet, psig = 185 = Back pressure at outlet, psig = 0 Kp = Overpressure sizing factor, 1% overpressure (From: Farris Book Page 3.7) = 0.07. Kg = Sizing factor for specific gravity * G = Specific Gravity Ku = Viscosity correction factor from curve on Page 3.8 = 1.0 Temperature of reactor at time of release = 109F. Reactor contained 34% Vinyl Chloride by volume. Specific Gravity of water @ 10SF = 0.99. Specific Gravity of Vinyl Chloride @ 109F = 0.87. Specific Gravity of Mixture = (0.34)(0.87) + (0.66)(0.99) 0.94 dTH 000088053 VL - (11.05) (24.3) V 1.25(185-0) (0.07) (1.03)/(l .0) 294 gallons per minute total discharge. @ 34% Vinyl Chloride Discharge of Vinyl Chloride = (0.34)(294) * 100 gallons per minute. or 725 #s VCM/Minute Vinyl discharged in two seconds: 725 #'s VCM X 1 Minute X 2 Seconds - 24 #s VCM Min. 60 Seconds . dTh 000088054
