Stability -I : Chapter 1

Exact ullage where pump should be shut = (2.898 + 0.5)m
                                                                             = 3.398m.
  1. A tank with a horizontal base and vertical sides is 10m deep and has rectangular trunkway 1m high. The volume of the tank alone is 8000m3 and that of the trunkway 500m3 . Find the ullage when 5320t of vegetable oil of RD 0.7 is loaded.
Given :

The depth of tank = 10m
Height of the trunkway = 1m
Volume of the tank alone =8000m3
Volume of the trunkway = 500m3
The mass of the oil =5320 t
RD =0.7qes7

We know that :
Density = (mass /volume)
Volume   = mass /density
 = (5320 /0.7)
 = 7600m3

Depth of oil = (volume /area)
= (7600/800)
=9.5m

Ullage insides the tank = (10 – 9.5)
=0.5m
