temperature is about 120˚F, 2.5 gallons per minute
2006-10-26 07:17:06 · update #1
delta T = 120˚F-50˚F (initial temperature) = 70˚F
2.5 gallons per minute * 8 lbs/gal = 20 lbs/min
20 lbs/min * 10 min = 200 lbs
200 lbs * 70˚F = 14000 BTU
divide 14000 BTU by the efficiency of the water heater to get the total heat input.
Then take the heating value of the gas (BTU/unit volume or whatever), and divide by the total heat input to get the volume of the gas.

You can't calculate this without knowing how much water is delivered per minute by the water pressure and the temperature of the water to be used.

None if it's a cold shower.
