An office heater puts out 2070 Btus (British thermal units) of energy in the form of heat per hour. Given that 1 Btu = 1.055 kJ, how many megajoules of energy in the form of heat can be produced per year (365 days) by the heater (assume continuous operation)?
19130.526MJ/HR
2070 BTU/hr x 24 hr/day x (365 days/yr) x 1.055 kJ/BTU x (1 megajoule/1000 kJ) = ?
To calculate the amount of energy in the form of heat produced per year, we need to convert the Btus to megajoules and then multiply by the number of hours in a year.
Step 1: Convert Btus to kilojoules
1 Btu = 1.055 kJ
2070 Btus * 1.055 kJ/Btu = 2183.85 kJ
Step 2: Convert kilojoules to megajoules
1 kJ = 0.001 MJ
2183.85 kJ * 0.001 MJ/kJ = 2.18385 MJ
Step 3: Calculate the energy produced per year
Since the heater operates continuously, we will multiply the energy produced per hour by the total number of hours in a year.
2.18385 MJ * 365 days * 24 hours/day = 19,107.9 MJ
Therefore, the office heater can produce approximately 19,107.9 megajoules of energy in the form of heat per year.
To find the number of megajoules of energy in the form of heat produced per year by the office heater, we need to calculate the total amount of energy produced in kilojoules and then convert it to megajoules.
First, let's calculate the total energy produced by the office heater in one hour:
2070 Btu/hour * 1.055 kJ/Btu = 2184.85 kJ/hour
Next, let's find the total energy produced by the heater in one day:
2184.85 kJ/hour * 24 hours/day = 52436.4 kJ/day
Finally, let's calculate the total energy produced by the heater in one year:
52436.4 kJ/day * 365 days/year = 19128726 kJ/year
To convert the energy to megajoules, we divide by 1000:
19128726 kJ/year / 1000 = 19128.726 MJ/year
Therefore, the office heater can produce approximately 19128.726 megajoules of energy in the form of heat per year, assuming continuous operation.
