The specific heat of water is 1 BTU per pound per degree Fahrenheit. There are 8.3378 lbs/gallon at 60 degrees, which equals 3251.742 pounds of water. The number of BTUs to raise it 188 degrees is then 611,327.496 BTUs.
Heating a gallon of water by one degree Celsius requires around 8,337 BTUs (British Thermal Units) of energy. Since 1 cubic foot of natural gas produces about 1,031 BTUs, you would need roughly 8 cubic feet of natural gas to heat a gallon of water by one degree Celsius.
BTUs, or British Thermal Units, measure the amount of heat energy required to raise the temperature of one pound of water by one degree Fahrenheit. The formula to calculate BTUs is: BTUs = weight of water (in pounds) x temperature change (in degrees Fahrenheit) x 1. Alternatively, the formula can be expressed as: BTUs = (Flow rate in gallons per minute x change in temperature in degrees Fahrenheit) / 500.
The heat content of a gallon of water at a certain temperature can be calculated using the specific heat capacity of water (1 calorie/gram °C). For example, to calculate the heat content of a gallon of water at 20°C, you would need to know the mass of the water and apply the formula: heat content = mass of water x specific heat capacity x temperature change.
To determine the BTUs that must be removed from one pound of water at 200°F to convert it to ice at 30°F, we need to account for several steps: cooling the water from 200°F to 32°F (the freezing point), the phase change from water to ice at 32°F, and then cooling the ice from 32°F to 30°F. Cooling the water from 200°F to 32°F requires about 168 BTUs (1 BTU cools 1 pound of water by 1°F). Freezing the water at 32°F requires the removal of 80 BTUs (latent heat of fusion). Cooling the ice from 32°F to 30°F requires an additional 2 BTUs. In total, approximately 250 BTUs must be removed (168 + 80 + 2 = 250 BTUs).
That's going to depend on . . . -- the starting temperature of the water -- the target temperature of the water -- how fast you want it to get there -- the efficiency of the heater you use
You would need to remove approximately 1200 BTUs of heat to convert a gallon of water to ice. There are 8.34 lb in a gallon of water, which converting to lb-moles is 0.463. The latent heat of crystallization for water is -2583.4 BTU/lb-mole. Multiplying the two together and you get -1197 BTUs, which means you need to remove that amount of heat to convert the gallon of water to ice.
To heat one gallon of water by 50 degrees Fahrenheit, you need approximately 0.2 therms of energy. This is based on the fact that it takes about 8.33 BTUs to raise the temperature of one gallon of water by one degree Fahrenheit, totaling around 416.5 BTUs for a 50-degree increase. Since one therm is equivalent to 100,000 BTUs, the calculation gives you about 0.00416 therms per degree, resulting in roughly 0.2 therms for the total increase.
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.
To calculate the BTUs removed per hour, use the formula: BTUs = flow rate (lbs/min) × temperature change (°F) × 1.0 (specific heat of water). First, convert the flow rate to pounds per hour: 10 lbs/min × 60 min/hour = 600 lbs/hour. Then, calculate the BTUs: BTUs = 600 lbs/hour × 15°F × 1.0 = 9,000 BTUs/hour. Thus, 9,000 BTUs of heat are removed per hour.

That depends on what the starting temperature of the water is,and what temperature you want it to reach.If you expect to get a number, you must first give the necessary numbers.
Heating a gallon of water by one degree Celsius requires around 8,337 BTUs (British Thermal Units) of energy. Since 1 cubic foot of natural gas produces about 1,031 BTUs, you would need roughly 8 cubic feet of natural gas to heat a gallon of water by one degree Celsius.
100 BTU if it's Fahrenheit
To change 10 pounds of ice at 20 degrees Fahrenheit to steam at 220 degrees Fahrenheit, you need to supply enough energy to first melt the ice, then heat the water to the boiling point, and finally convert it to steam. This process requires approximately 180 BTUs per pound of ice to melt it, 180 BTUs per pound of water to heat it to the boiling point, and then 970 BTUs per pound of water to convert it to steam. So, for 10 pounds of ice, the total BTUs required would be around 18,300 BTUs.
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.
The number of BTUs required to maintain water at 150 degrees Fahrenheit depends on several factors, including the volume of water, ambient temperature, and heat loss due to evaporation and conduction. For example, to heat one gallon of water from room temperature (around 70°F) to 150°F, you would need approximately 80 BTUs. To maintain that temperature, you'd need to calculate the heat loss based on the specific conditions of your environment. This can vary widely, so it's essential to consider those factors for an accurate estimate.
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.
