What does 18000 12000 btu mean?
18000 BTU means TON 1.5 ,12000 BTU means 1 TON
How many square feet of heating surface is equal to one BTU?
how many btu does a 125 hp boiler produce on #2 oil
How many square feet will 140000 btu's heat?
It doesn't work that way. BTU is a unit of energy, not a unit of power. In other words, to heat a certain building you would need a certain amount of BTU per hour, a certain number of BTUs per second, or some other unit of power.
How many square feet does an 8000 BTU air conditioner cool?

How many Btu are required to change 600 pounds of water at 75 degrees F to steam at 212 degrees F?
1 BTU is required to raise 1lb of water 1 degree F in 1 hour. 212-75=137 degrees 600 lbs water x 137 degrees= 82,200 BTU's required to change 75 degree water to 212 degree water. To change 212 degree water to 212 degree steam it requires 970 btu's (latent heat of vaporization) per lb of water 970 btu x 600 lbs water = 582,000 btu Answer - 582,000 btu+ 82,200 btu = 664,200 btu's
How many BTU are required to lower the temperature of one gallon of water one degree?
No BTU are required in order to lowerthe temperature of water. All you have to dois place the water in an environment that is cooler than the water is, then stand backand watch the temperatue of the water drop while the BTU flow out of it.
What is ton of ac?
! ton of refrigeration is 12,000 BTU's. 1 BTU is the energy required to raise or lower 1 lb of water 1 degree F.
How many BTU are required to raise the temperature of one gallon of water one degree Fahrenheit in one hour?
This is a pretty straightforward calculation. By definition, a BTU is the amount of energy required to raise one pound of water one degree F. But you have one gallon of water, which weighs approximately* 8.34 pounds. So, you'd need 8.34 BTU to increase one gallon of water one degree F. Note how the amount of time was not important. Whether you heat the water slowly or quickly doesn't matter. You will still require 8.34 BTU to raise the temperature of a gallon of water one degree F. * I say approximately because the weight of water varies slightly with its temperature. Water is at its densest at 4 degrees Celsius (39 degrees F). A gallon of water at temperatures above and below that value will weigh less.
How many btu's are required to change 1 pound of water to 1 pound of ice?
Depends on the temperature of the water. If it is 32 degree water and you want 32 degree ice then you need a -144 BTU loss to change state from liquid to solid. It takes 1 BTU to raise the temperature of 1 pound of water 1 degree (F). If the water is 82 degrees then you would need a -50 BTU loss (+) 144 BTU to change state. TOTAL WEIGHT OF WATER (X) 1 BTU (X) Degrees desired of change. If it is ICE to WATER then it is the TEMP of ICE (X) .5 BTU (X) NUMBER OF DEGREES INCREASED = TOTAL BTU needs. If you change state in the process you have to add 144 BTU for 32 degree ICE to 32 degree WATER and 970 BTU for 212 degree WATER to 212 degree STEAM but only when you change state.
How many Kwh does it take to increase 1 gal one degree F?
1 gallon of water weighs 8.34 pounds. It takes I BTU to change the temp of 1 pound of water 1 degree F. So for 1 gallon it takes 8.34 BTU. It takes 3412.14 BTU to equal 1 KWH. So 8.34 Btu x (1KWH / 3412.14 BTU) = 0.002444 KWH
What does a 30000 btu burner mean?
Answer:A BTU is the amount of heat energy required to raise 1 pound of water by 1 degree Fahrenheit. So a 30,000 BTU burner can heat 30,000 pounds of water by 1 degree Fahrenheit. Any multiple of the amount of water and the temperature rise that yields 30,000 is equivalent.And 30 000 BTU equal 31 651,68 kilojoules.Usually it is more meaningful to rate a heating device in BTU/hour.
What is the quantity of heat required for changing the temperature of one pound of water one degree fahrenheit- One TBU - Heat- One UBT or One BTU?
British Thermal Unit (BTU)
How many btu's to raise 1 liter of water 1 degree?
There are 3.966 BTU in a kilocalorie (kcal), and 1 kcal raises 1 kg of water 1 degree C, but to work through it:1 BTU raises 1 pound of water 1 degree F, and 1 kg = 2.20 pounds, therefore:2.20 BTU raises 1 kg of water 1 degree F, and 1 litre of water weighs 1 kg (basically), therefore:2.20 BTU raises 1 litre of water 1 degree F, and a 1 degree change in F equals 5/9 degree C, therefore:2.20 BTU raises 1 litre of water 5/9 degree C, therefore:3.96 BTU raises 1 litre of water 1 degree C.
How many btu per gallon of water?
It takes 8.33 BTU to raise the temperature of water 1 degree F.
How much BTU's are in a 12ounce water?
It takes 1 BTU to raise 1 lb of water per degree Fahrenheit.
How many BTUs does it take to heat one pound of water from 80 degree F to 212 degree F?
212 - 80 = 132 degrees temperature increase x 1 pound water = 132 BTU
