Purging long gas supply

[mutley racers]

I have a job where I need to run 30 metres of 28 mm and 10 metres of 22mm copper tube. Now there is no gas hob in the place so I need to light the gas while purging. What right do you guys make up in this scenario. Cheers

g4 i make it 0.04401m3

So to calculate the installation volume it is G4 metre 0.008 + 30 metres 28 mm 0.0162 + 10 metres 22mm 0.0032 + 10 % for fittings is 0.0301?

Have I made a mistake some where

must be! 30mx28mm is 0.0387m3 & 10mx22mm is 0.01728m3 !!

according to the rays gas app...
30mx28mm + 10mx22mm not adding any fittings its 0.04401m3 or 0.04614m3 with fittings!!

think youve been hoping to do it in 10mm aint u? lol
