30000btu convert to watts
BTU is not a measure of temperature.
230,000 btu
How hot and how fast? 5,000 btu's will heat it. Not very hot and it will take forever. If you are using it for residential hot water application. Roughly 40,000 BTU's
300
Almost 340,000 BTU per hr
To convert cubic feet per hour (cfh) to BTU (British Thermal Units), you would need to know the heat content of the gas being used. If we assume natural gas with a heat content of 1,000 BTU per cubic foot, then 3000 cfh would be equivalent to 3,000,000 BTU per hour.
Which does the trouble belong to? Is it your Acer Aspire 3000 laptop? Or is your laptop Acer Aspire 3000 battery hot? .
A typical home boiler uses 3000 Watts. 3000 watts is not the correct answer. Watts = volts x amps, or if converting to btu 3000 watts = 10236 btu. At typical household votage of 120, 3000 watts would equal 25 amps and no boiler uses that much current and if your desire is to convert btu to watts I would suspect the average boiler output is far greater than 10K btu. Determine the output in btu/hr of the boiler in question from the MFR`s nameplate and divide by 3.412 3.412btu=1watt/hr. My home boiler uses 3000 watts, it's in my kitchen cupboard and it runs on a 240 v supply.
1 BTU = 1.055 kilojoules. For a nuclear plant with an electrical output of say 1000 MWe, the reactor thermal output will be about 3000 MW (at 33 percent efficiency), or 3000 Mega joules/second, which is 3000 x 1000 kilojoules/sec, or 3000/1.055 x 1000 BTU/sec. this reduces to 2.84 x 106 BTU/second, Scale it according to the actual electrical output of the plant.
Ratings are per hour. Divide 10,000 by 60 minutes per hour.
15000 BTU/hr is equivalent to approximately 139,500 BTU/day. To convert this to Fahrenheit, you would need to consider other factors like the specific heat capacity of the material involved. Temperature is a measure of the average kinetic energy of the particles in a substance, which is different from the energy being produced by the 15000 BTU/hr.
