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)

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:
http://www.thermexcel.com/english/program/gasus1.htm 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 ;-)
