Gas pipe sizing

[Nigel Molesworth]

Has anyone got a gas pipe calculator?

I'm installing a gas pipe for a RangeMaster Elan Dual Fuel cooker (installation will be checked later by a CORGI fitter)

The details are as follows:

LP Gas (Propane) Approx 6m run of copper pipe, 2 elbows + 1 bend, around 15 kW total:

2x Wok burners 3.5kW (246g/h) 1x Large Burner 3.0kW (210g/h) 2x Medium Burners 1.7kW (119g/h) 1x Small Burner 1.0kW (70g/h)

This any good to you:

Copper Tube Sizing it's the manual version but you can use a calculator if you want :-)

Thanks, but I'm not sure it applies to LPG, it has a different standard: BS 5482-1: 2005. Has anyone got a copy?

You're right, I thought it would be ok as it was based on volumes, not calorific value but of course it says for gas of relative density 0.6 whereas LPG is 1.4-1.53 (apparently).

A quick google for LPG +pipe +size or sizing gets the AeroGas calculator:

which looks way OTT but there is a free eval download available and it has tables for LPG & a lot of other gasses. Perhaps a quick play with that proggy could give you a scaling factor for the Copper Development Assoc site calculator.

Thanks again, but I'd tried it - the program says "Demo expired". I've contact them and see if I can get it fixed.

Doh!, perhaps try an uninstall (if there was an install), then turn your pc clock back a few years & try again. Other than that I think I'd best leave you to it as my suggestions seem to be causing more work with little success ;-)
