Hence, Ullage = (1 -0.66)
= 0.33m

A rectangular tank has a total depth of 10.5m and volume 8200m3, which include a trunkway of depth 0.5 m and volume 200m3 . find the mass of oil of oil of RD 0.8 loaded and the ullage, if 2% of the volume of the tank is left for expansion.
Given :
Depth of the tank is = 10.5m
Volume of the tank = 8200m3
Depth of the trunkway = 0.5m
Volume of the trunkway = 200m3
RD of the oil = 0.8
According to question, 2% of the tank volume left for expansion .
Volume of the tank alone = (8200-200)
= 8000m3
Height of the tank alone = (10.5 -0.5)
= 10 m
2% of the volume of the tank left for expansion .
= (2/100 x 8200)
=164m3
Volume of the oil to be load = (8200 -164)
=8036 m3
Mass of oil to be load = ( volume x density)
= (8036 x 0.8)
= 6428.8t
Volume of the trunkway = (L x B x 0.5)
= 200m3 ( given)
We can calculate Area as = (200 /0.5)
=400m2
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
