there is no conversion from temperature to BTU unless you know the mass and specific heat of a substance at a certain temperature. Then you could calculate the BTU required to heat the substance from a known starting temperature up to an ending temperature.
One measure does not directly translate to another. A BTU is the amount of heat that it takes to raise the temp of one pound of water by one degree F. A burning match, and a burning fireplace may both be at 650 degrees, but the fireplace gives off more heat (more BTUs)
To calculate the BTUs required to raise the temperature of 15 pounds of water, you can use the formula: BTUs = Weight of water in pounds × Temperature change in degrees Fahrenheit × 1 BTU So, the calculation would be: BTUs = 15 lbs × (130°F - 100°F) × 1 BTU = 15 lbs × 30°F = 450 BTUs.
313 Btu
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.
To calculate the BTUs needed to raise the temperature of a 40-gallon water heater by 60 degrees Fahrenheit, you can use the formula: BTUs = gallons × temperature rise × 8.34. For a 40-gallon heater, it would be 40 gallons × 60°F × 8.34 BTU/gallon°F, resulting in approximately 20,016 BTUs. Therefore, it takes about 20,016 BTUs to achieve that temperature increase.
650 degrees Celsius is equivalent to 1202 degrees Fahrenheit.
To change 5 pounds of ice at 20°F to steam at 220°F, you will need to go through multiple phases: raise ice temperature to 32°F, melt ice to water at 32°F, raise water temperature to 212°F, and then convert water to steam at 212°F to steam at 220°F. The total heat required, in BTUs, is around 503 BTUs per pound of ice, which translates to about 2515 BTUs for 5 pounds of ice.
It takes approximately 144 BTUs to change one pound of ice at 20°F to water at 212°F, and an additional 970 BTUs to change the water to steam at 220°F, for a total of 1114 BTUs.
650 degrees Celsius is equal to 1202 degrees Fahrenheit. You can convert Celsius to Fahrenheit by multiplying by 9/5 and then adding 32.
There are no units for the temperature. The temperature change could be 230 Celsius degrees or 170 Fahrenheit degrees (94 Celsius degrees). In fact they could be in less commonly used units: eg Reaumur.
To determine the BTUs required to heat lard to 390 degrees Fahrenheit, you need to know the starting temperature and the amount of lard you're heating. The specific heat capacity of lard is approximately 0.5 BTU/lb°F. For example, if you have 1 pound of lard at room temperature (about 70°F), it would require about 160 BTUs to reach 390°F, calculated as follows: (390°F - 70°F) × 0.5 BTU/lb°F = 160 BTUs. Adjust the calculation based on the actual weight and starting temperature of the lard.
To calculate the BTUs removed per hour, you can use the formula: BTUs = flow rate (lbs/min) × temperature change (°F) × 1. If the flow rate is 10 lbs/min and the temperature change is 15°F, the calculation is: 10 lbs/min × 15°F × 1 BTU/lb°F = 150 BTUs/min. To find the hourly rate, multiply by 60 minutes, resulting in 9,000 BTUs per hour.
