How much would 1 cubic ft of gas last at home

[dkatwa]

Silly question

When gas is extracted from the ground, I presume it is in liquid form. However, it is supplied to the home as a gas.

My question is, how much would 1 cubic foot of gas (as a liquid) last at home, say, for an average sized gas cooker?

Is it an hour, days, a month?

1 cubic foot at what pressure?

He asked about 1 cubic ft of liquid gas- its already as compressed as it can be.

LNG is about 20000BTU/lb, so how much does 1 cubic ft weight?

From our friends at the US department of energy - http://energy.gov/sites/prod/files/2013/04/f0/LNG_...

LNG is about 456kg/m3, which, unless I'm being dense is about 12.9kg/ft3, or 24.4lbs.

And if you're keeping this at home you must have a bloomin good fridge.

How long does a bottle of calor/lpg last... rather depends on how much you're using.

LNG is about 600 times smaller than the methane as gas.

It comes out of the ground as a gas - its liquified to allow transport across oceans mainly where running gas pipelines wouldn't be practical.

Oven uses 30/50 ft3/hr - so one cubic foot of gas would last around 90 seconds. the equivalent amount of re-gassed LNG about 15 hours.
