Total ullage = (1 +0 .5)
= 1.5m.

A rectangular tank has a total depth of 21m and volume of 20600 m3, which includes of trunkway of depth 1m and volume 600m3. find the ullage when 16320 t of oil of RD 0.8 is loaded.
Given :
The total depth of tank =21m
Volume of the tank = 20600m3
The height of the trunkway = 1m
Volume of the trunkway = 600m3
Oil loaded = 16320t
RD= 0.8
The height of the tank = (21-1)
= 20m
Volume of the tank= (20600 – 600)
=20000m3
Area of tank = (20000 /20)
=10000m2
Volume of the oil = (mass /density)
=(1620 /0.8)
= 20400 m3
Hence, Volume of the oil inside the trunkway = (Total volume of the oil – volume of the tank)
= (20400 – 20000)
=400m3
Depth of the oil = (volume /area)
= (400/600)
= 0.66m
no 2
mass of oil 1646.2 Ton
please check this
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
