在LR规范中,对舱底水管径选择要求如下:
The diameter, db, of branch bilge suction pipes to cargo and machinery spaces is to be not less than required by the following formula, to the nearest 5 mm, but in no case is the diameter of any suction to be less than 50 mm:
如何理解 to the nearest 5 mm,
比如现在计算管子内径为129mm,在管子规格中有140X5,140X7,140X9.5 按规范理解140X5的满足要求,140X7或140X9.5是否满足要求?
the nearest 5 mm ,是指向上取5或是只±5mm,都可以?如何理解这句话。
