Problem 10
A homeowner is trying to decide between a high-efficiency natural gas furnace with an efficiency of 95
percent and a ground-source heat pump with a COP of 3.3. The unit costs of electricity and natural gas are
$0.112/kWh and $1.44/therm (1 therm = 105, 500 kJ). Determine which system will have a lower energy
cost.

- Consider a 400-MW, 32 percent efficient coal-fired power plant that uses cooling water withdrawn from a nearby river (with an upstream flow of 10-m3/s and temperature 20 °C) to take care of waste heat. The heat content of the coal is 8,000 Btu/lb, the carbon content is 60% by mass, and the sulfur content is 2% by mass. How much electricity (in kWh/yr) would the plant produce each year? How many pounds per hour of coal would need to be burned at the plant? Estimate the annual carbon emissions from the plant (in metric tons C/year). If the cooling water is only allowed to rise in temperature by 10 °C, what flow rate (in m3/s) from the stream would be required? What would be the river temperature if all the waste heat was transferred to the river water assuming no heat losses during transfer? Estimate the hourly SO2 emissions (in kg/h) from the plant assuming that all the sulfur is oxidized to SO2 during combustion.arrow_forwardHow do I convert 10649 KWh into (KWh/(m2-yr)?arrow_forwardPlease help solve both for my homework.

- What is the best definition for non- renewable energy? O a. It is energy collected by humans that can be replaced after five to ten years. O b. It is energy from finite sources that cannot be replaced by natural means at a quick pace of time. O c. It is energy from finite sources that can be replaced after using them. O d. It can be measured in joules or kilowatts.arrow_forwardWater falls from a height of 500 m and the mass of water is 50 kg. What is approximately the rise in temperature of water at the bottom if the whole energy is used to heat the water? Specific heat of water is 4.18 kJ/kg-deg C. O 5000 deg C O 1173 deg C O 500 deg C O 0.23 deg C O none of the abovearrow_forwardWe have exposed 1 kg of water, 1 kg of brick, and 1 kg of concrete each to a heat source that puts out 100 J every second. Assuming that all of the supplied energy goes to each material and they were all initially at the same temperature, which one of these materials will have a greater temperature rise after 10 s? We can answer this question using Equation as shown . We will first look up the values of the specific heat for water, brick, and concrete, which are cwater = 4180 J⁄kg K, cbrick = 960 J⁄kg K and cconcrete = 880 J⁄kg K . Now applying as shown , Ethermal = mc(Tfinal Tinitial) to each situation, it should be clear that although each material has the same amount of mass and is exposed to the same amount of thermal energy, the concrete will experience a higher temperature rise because it has the lowest heat capacity value among the three given materials.arrow_forward
