(2) Dr. Schrader built a supercomputer in his home because he does not understand the concept of work/life balance. During the recent cold weather experienced in the Dayton region, his home

was rated to lose heat at 75,000 BTU/h. The combination of his body heat, heat given off from lighting, and the heat produced from the supercomputer total to a rate of 8000 BTU/h that is added to the home. Qheat Qgen Super Comput er Qloss Coal Energy Content: 36 MJ/kg Emissions: 5720 lbs CO2 per 2000 lbs coal burned Part A: To maintain the house at a steady, constant temperature what is the heat rate (BTU/h) that must be delivered from his heating unit? Part B: Dr. Schrader needs assistance analyzing the home's heating needs. What is the total quantity (BTU) of heat required to maintain a steady heating rate for 48 hours? Part C: Dr. Schrader learns that the energy for his heating unit is sourced from a coal-fired power plant. Assuming a perfectly efficient process that extracts the stored chemical energy in coal and converts it to electricity, what is the quantity of coal (kg) consumed to heat the home during 48 hours? Part D: What is the quantity (kg) of CO₂ emissions produced to heat the home for 48 hours?
