∙ 9y agoThe amount of energy that is required to 160 cfm of air from 10 to 170 degrees F is 200 btu. T he formula is weight x specific heat x temperature difference so we have10 pounds x 1.00 x 2010 for 10 pounds of water.

∙ 9y agoThe energy required to raise the temperature 1 degree Celsius of 1 gram of water (1 mL) is 1 calorie (=4.18 J). So for 1 kg, 1Kcal (= 4180 J = 4.18 KJ) is required. To raise it 60 degrees, just multiply by 60 and for 10 kg multiply by 10 again. That would make 2.508 MJ (= 2508000 J) Now this is not completely accurate. The energy required to raise the temperature of water differs at 20 degrees from that at 60 degrees. The difference is small (~0.05 J or something like that) but still present.

That will completely depend on how much water there is.
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.
It doesn't work that way. There is not a certain number of btus to raise air temperature. You would have to know how much air. A BTU is the British Thermal Unit. That is the amount of energy required to raise the temperature of one pound of water one degree F.
The amount of energy required to raise the temperature of 1 kg of water by 1 degree Celsius is approximately 4,186 Joules. Therefore, to raise the temperature by 2 degrees Celsius, you would need about 8,372 Joules of energy.
The amount of heat energy required can be calculated using the formula: Q = mcΔT. Given m = 0.362 kg, c = 390 J/kg°C for copper, and ΔT = (60.0 - 23.0) = 37.0 °C, plug these values into the formula to find the heat energy required to raise the temperature of the copper.

To raise it 60 degrees, just multiply by 60 and for 10 kg multiply by 10 again. That would make 2.508 MJ (= 2508000 J) Now this is not completely accurate.

The specific heat capacity of aluminum is 900 J/kg°C. The change in temperature is 3°C. Using the formula Q = mcΔT, the energy required would be 0.2 kg * 900 J/kg°C * 3°C = 540 J. So, the energy required to raise the temperature is 540 Joules.
The specific heat capacity of water is 4.18 J/g°C. To calculate the energy required to raise 21 kg of water by 2 degrees Celsius, use the formula: Energy = mass x specific heat capacity x temperature change. Plugging in the values, the energy required is 21,084 Joules.
The specific heat capacity of aluminum is 0.9 J/g°C. To calculate the energy required to raise the temperature of 0.2kg of aluminum by 3 degrees Celsius, you would use the formula: Energy = mass x specific heat capacity x temperature change. Substituting the values into the formula, Energy = 0.2kg x 0.9 J/g°C x 3°C = 0.54 Joules.
The specific heat capacity of iron is 0.45 J/g°C. To raise the temperature of 3kg (3000g) of iron by 5 degrees Celsius, you would need: 3000g x 0.45 J/g°C x 5°C = 6750 Joules of energy.
To find the energy required to raise the temperature of water, you can use the formula: Energy = mass x specific heat capacity x temperature change. The specific heat capacity of water is 4.18 J/g°C. Therefore, the energy required to raise 7.3 kg of water from 10°C to 90°C would be 7.3 kg x 4.18 J/g°C x (90°C - 10°C).
The specific heat capacity of silver is 0.235 J/g°C. The energy required to raise the temperature of 3 g of silver by 5°C can be calculated using the formula: Energy = mass * specific heat capacity * temperature change. Plugging the values in gives: Energy = 3 g * 0.235 J/g°C * 5°C = 3.525 J.
The amount of heat energy required to raise the temperature of a substance can be calculated using the formula: Q = mcΔT, where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. First, calculate the change in temperature (220°C - 20°C = 200°C), then use the specific heat capacity of the substance to find the heat energy.
