LPG injector size?

[Knappers]

Maybe I'm being a bit lazy but can anyone help me with the output of jets/nozzles by size on LPG at around 30mb?
Its not thrilling but I'm looking at some redneck style testing on campervan ventilation requirements (BS EN 721 clause 6, if anyone's as bored as me).

With a fair bit of guessing I'm thinking
1.6kw - .71
1.8kw - .75
2.0kw - .80
But I could be well out?
Propane

To be extra rough does anyone know if carb jets are sized the same as gas ones
