Re: Clarify the size of pipe as over a length Is the pipe length between 40–50 meters acceptable? If so, what does ‘over’ do in ‘over 40-50 meters’? If you mean you would accept the length if it falls within the range, ‘over’ doesn’t mean much here?
I would say ‘… 10cm DIA (for diameter) pipe …’ or ‘… 10cm Ø (std. drafting symbol for diameter) pipe …’ I prefer to see ‘… pipe diameter of 10cm (nom., I.D.(for Inside Diameter) or O.D.(for Outside Diameter)) is an appropriate size for the design of the water system.’ |
