Modelling of Boil-Off Gas in LNG Tanks
... four of the LNG tanks’ BOG levels reached 0.05vol%/day. In order to satisfy the BOG design requirement, the operating pressure of the four large LNG tanks in the case study was maintained above 200mbar. Thus, the operating pressure impacts BOG on LNG tanks, but this effect is limited under the extre ...

... Since the crate is doing uniform motion (constant velocity), acceleration a=0. According to Newton’s 1st Law, if a⃗⃗ = 0, ∑ ⃗F⃗ =0. In the horizontal direction, there are only two forces acting on the crate: the exerted 50N force and the unknown frictional force. These two must add up to be 0. So th ...
