A NET CAPACITY WITHIN BUNDWALL

i) GROSS CONTAINMENT CAPACITY

LENGTH OF NEW BUNDWALL (INSIDE DIMENSION) Lb1 = 21.00 mWIDTH OF NEW & EXT'G BUNDWALL (INSIDE DIMENSION) W1 = 29.50 mINTERNAL HEIGHT OF EXT'G BUNDWALL Hb1= 1.40 mNEW CONTAINMENT CAPACITY Vg1 = Hb1 * W1 * Lb1 = 867.30 m3

LENGTH OF EXT'G BUNDWALL (INSIDE DIMENSION) Lb2 = 42.00 mWIDTH OF NEW & EXT'G BUNDWALL (INSIDE DIMENSION) W2 = 29.50 mINTERNAL HEIGHT OF NEW BUNDWALL Hb2 = 1.40 mEXT'G CONTAINMENT CAPACITY Vg2 = Hb2 * W2 * Lb2 = 1,735 m3

GROSS CONTAINMENT CAPACITY Vg =Vg1 + Vg2= 2,602 m3

CAPACITY DISPLACED BY EXT'G TANK (T-1417) Vf5 = 5.66 m3

GROSS CAPACITY DISPLACED BY FOUNDATIONVf = Vf1+ Vf2+ Vf3+Vf4+Vf5= 200 m3

ASSUME GROSS CAPACITY OF DISPLACED BY PUMP, PIPERACK Vp = 50 m3

STUMP, PIPING & OTHER ACCESSORIES APPROX.

iv) TOTAL DISPLACED CAPACITY Vd = Vt+ Vf + Vp = 693 m3

NET CAPACITY WITHIN BUNDWALL Vn = Vg - Vd = 1,909 m3

B NET CAPACITY DURING ONE TANK FAILURE

THE LARGEST TANK CAPACITYD = 13.8 m Vtank = 1,944 m3

H = 13 m

FIRE WATER CAPACITY DURING ONE TANK ON FIRE Vfire = 150 m3

(APPROXIMATE CAPACITY DURING 30 MIN. FIRE)

NET CAPACITY DURING ONE TANK FAILURE Vmax = Vtank + Vfire = 2,094 m3
