Hello, I need some help with my civil engineer homework. I am stuck on the last question
Electricity (See your home electricity bill)
1) You can obtain the daily kilowatt-hour, kWh, use for your home from the electricity bill. This ispresented differently from utility to utility. What is your monthly electricity use?1,186 kWh
2) Use 30 days equal to one month to find the average daily electric use.Daily amount: 39.53 kWh (I divided 1,186/30)
3) How many members are in your household?: 4 people
4) Your personal share is obtained by dividing the daily amount (above) by the number of people
(house members) in the household: 9.88 kWh
5) Add 1.6 kWh for electric use at work, in the office, or here at QCC. The total daily electric use foryou equals.personal share + 1.6 kWh =11.48 kWh
What is the Crude Oil equivalent?
*With electricity, 1 gallon of crude oil produces 15kWh of electricity. Divide your answer intocrude oil conversion factor, 15 kWh, to obtain the crude oil equivalent.

1) Heating the water in a 55-gallon water heater requires about 2.0 x 103 kJ of energy.
a) Assume the energy came from natural gas with 80% efficiency; how many grams of natural gas are required?
b) Assume the energy came from electricity with 80% efficiency and that the electricity was produced from the combustion of coal with 30% efficiency; how many grams of coal are required?
For problem above, calculate how much CO2 in grams is emitted to the atmosphere.
For a: Use the balanced equation for the combustion of methane (CH4) to determine how many grams of CO2are produced from the amount of natural gas required.
For b: Assume that coal produces 5.25 kJ of energy per gram of CO2 produced. Calculate how much CO2 in grams is produced.
A typical household of four people consume approximately 300 liters of water per day. Express the annual consumption rate of a city with a population of 100,000 people. Express your answer in liters per year and m3 per year.
