If you're in Celsius, 13459.5 Btu's. If you're in Fahrenheit, 12632.5 Btu's.
The current Canadian penny, in use since 2000 and consisting of 94% steel, 1.5% nickel, and 4.5% copper plating, has a mass of 2.35 grams. So it would take 194 of them to weigh one pound (avd.), on Earth.
212-65=147. 147(20)=2940 btu needed is this right?
One BTU is the energy required to raise one pound of water by one degrees. Therefore, your answer would be one half.
It takes 180 BTUs to raise 1 pound of water from 32 degrees Fahrenheit to 212 degrees Fahrenheit to convert it completely into steam. This change in temperature includes heating the water from its freezing point to boiling point, then undergoing phase change from liquid to gas.
at least 90 degrees
One pound of steam at 212 degrees Fahrenheit contains 1150 BTUs of energy.
To raise the temperature of 1 pound of water by 1 degree Fahrenheit, it requires 1 BTU (British Thermal Unit). Therefore, to heat water by 10 degrees, it would require 10 BTUs per pound of water. This value may vary slightly depending on the specific heat capacity of the water.
It depends on the composition of the steel as there are many different grades and types of steel.
To raise 1 pound of ice from 32°F to water at 32°F it requires 144 BTUs. Since you have 50 pounds of ice, you would need 50 * 144 BTUs to raise the ice to water at 32°F. To further raise the water from 32°F to 160°F, you would need an additional amount of BTUs based on the specific heat capacity of water.
That will completely depend on how much water there is.
0.104 btu
It takes 1 British Thermal Unit (BTU) to raise the temperature of 1 pound of water by 1 degree Fahrenheit. This measurement is a standard unit of energy used in heating and cooling calculations. Therefore, to raise 1 pound of water by 1 degree, you would need exactly 1 BTU.
0.0923Btu Specific heat of copper is 0.0923 Btu/lb F
That's going to depend on how much water you're responsible for. Teacup at 60 degrees . . . very few BTU. Swimming pool at 60 degrees . . . many more BTU. It's also going to depend on whether you're talking about Celsius or Fahrenheit degrees. Fahrenheit degrees . . . fewer BTU. Celsius degrees . . . more BTU. (Also, the water will escape as you pass 100.) In general, one BTU is approximately the energy required to raise the temperature of 1 pound of water 1 degree Fahrenheit. You can take it from there, when you reach the job site and determine the exact scope of the work.
