Exact ullage where pump should be shut = (2.898 + 0.5)m
= 3.398m.

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 =0.7
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
In question no 7, how did area 800 come…?
Volume of cylinder is pie X r X r X h
you are right
In Q9 I found ullage by subtracting
Total depth – Depth of oil
I got 0.21m but by using your method answer is coming correct..can you please explain me?
Got its!!
It’s very helpful for me ..thank you sir
Fantastic innovation
In Q8 area of tank should be 1000m2 not 10000m2
