Problema Solution
An office heater puts out 2070 Btus of energy in the form of heat per hour. Given that 1Btu= 1.055kJ, how many megajoules of energy in the form of heat can be produced per year(365 days) by the heater?
Answer provided by our tutors
365 days = 365*24 hours (since 1 day = 24 hours)
2070 Btus = 2070*1.055 kJ
Multiply the number of hours per year with the amount of kJ per hour:
2070*1.055*365*24 = 19,130,526 kJ
Since 1,000.00 kJ =1 MJ we have:
19,130,526 kJ = 19,130,526/1,000 MJ = 19,130.526 MJ produced per year.
