When a hydrocarbon fuel is burned, almost all of the carbon in the fuel burns completely to form CO2 (carbon dioxide). On average, 0.59 kg of CO2 is produced for each kWh of electricity generated from a power plant that burns natural gas. A typical new household refrigerator uses about 700 kWh of electricity per year. There are 50,000 households in the city.If the area of the city is 190 miles2, and if all that CO2 accumulates in the atmosphere, calculate the increase in CO2 concentration by weight in the atmosphere knowing that each cm2 of area carries a column of air that weighs 1 kg. If 1 mature tree absorbs 48 lbm of CO2 per year, what is the ratio of trees to households this city should have to counter the effect of refrigeration?

Consider a fuel cell vehicle. The vehicle draws 30 kW of power at 60 km/hr and is 50% efficient at rated power. (It converts 50% of the energy stored in the hydrogen fuel to electric power.) You are asked to size the fuel cell system so that a driver can go at least 300 km at 60 km/hr before refueling. Specify the minimum volume and mass requirements for the fuel cell system (fuel cell + fuel tank) given the following information:a. Fuel cell power density: 1 kW/L, 500 W/kg b. Fuel tank energy density (compressed hydrogen): 4 MJ/L, 70 MJ/k
According to the U.S. Geological survey, the volume of water in oceans, seas, and bays is 1.41 ✕ 1018 m3. The average concentration of naturally occurring uranium in seawater is 3.15 ✕ 10−6 kg/m3. If 0.670% of naturally occurring uranium is the fissionable isotope U-235 and each fission reaction yields 200 MeV, estimate the amount of time the uranium in the seawater on the planet could meet the planet's energy needs at an average usage of 1.94 ✕ 1013 J/s.
In a company there are the following consumptions for energy and energetics. The company works 8hours a day and consumes an average of 10 kWh/day of electrical energy, its thermal energy production system(heating) works through the combustion of a gas that provides 111.76 kcal/h for each gram that isgas flaring, using an average of 0.25 lbm/h of gas.Fuel is also used in another thermal system that on average consumes 1 lbm/h, whose density is 1.1g/mL with calorific value of 1193.45 BTU/lbm.

Solar ponds are small artificial lakes of a few meters deep that are used to store solar energy. The rise of heated (and thus less dense) water to the surface is prevented by adding salt at the pond bottom. In a typical salt gradient solar pond, the density of water increases in the gradient zone, as shown, and the density can be expressed as ρ = ρ0√1 + tan2(?/ 4 s/ H) where ? 0 is the density on the water surface, s is the vertical distance measured downward from the top of the gradient zone (s = −z), and H is the thickness of the gradient zone. For H = 4 m, ?0 = 1040 kg/m3, and a thickness of 0.8 m for the surface zone, calculate the gage pressure at the bottom of the gradient zone.

In the United States, energy for household heating is generally sold using English units, e.g., therm, gal, and cord. A house in Wisconsin uses 1200 therms of thermal energy during the heating season. Calculate the cost of fuel if the furnace uses (a) natural gas with an efficiency of 70%; (b) No. 2 fuel oil, efficiency 65%; (c) kerosene, efficiency 99.9% (unvented); and (d) wood with l5% moisture with an efficiency of 50%. Use the data in Tables 2.2, 2.7, and 2.13. The efficiencies are based on the HHV. Assume the cost of natural gas is $8/MBtu, the cost of No. 2 fuel oil is $3/gal, the cost of kerosene is $3.50/gal, and the cost of wood is $100/cord. Assume the bulk density of cord wood is 30 lbm/ft3 .
A mining company depleted more than half of its ore reserves and is no longer using all of its shaft infrastructure. It considers using one of the old shafts for pumped-storage hydro-electricity generation. This means that water will be pumped to the higher level, which is 1 000 m above the bottom level, at night when Eskom charges lower, off-peak, rates. The “higher level” will be changed into a dam (reservoir) by means of plugs that will be installed in some tunnels. The stored water has potential energy, which will be used to generate electricity for the mine at peak hours, when electricity is expensive. The pump that will be installed at the bottom of the column will also be used as a turbine for the generation of electricity The pump-as-turbine (PAT) must pump water to a height of 1 000 m through a column with an internal diameter (ID) of 345 mm. 3.1. Calculate the velocity of the water in the pipe if the quantity of water to be pumped is 220 litres per second (lps). 3.2.…
