The estimated energy one person uses in one round-trip from Phoenix to London to Phoenix is approximately 2.5 million joules.
To estimate the energy used by one person on a round-trip flight from Phoenix to London to Phoenix, we need to consider the energy consumption of the airplane and divide it by the number of passengers.
Let's assume the airplane consumes an average of 1 gallon (3.785 liters) of jet fuel per mile (as a rough estimation).
The distance from Phoenix to London is approximately 5,334 miles (8,577 kilometers) in a direct flight path.
To calculate the energy content of the fuel, we need to know its energy density. Jet fuel typically has an energy density of around 35 megajoules per liter (MJ/L).
Energy content of the fuel for one mile:
1 gallon ≈ 3.785 liters
Energy content per mile = 3.785 L/mile * 35 MJ/L
Energy content per mile = 132.475 MJ/mile
Total energy consumption for the round trip:
Energy consumption = Energy content per mile * Total distance
Total distance = 2 * 5,334 miles
Total distance = 10,668 miles
Energy consumption = 132.475 MJ/mile * 10,668 miles
Energy consumption = 1,412,795 MJ
Now, we need to divide this total energy consumption by the number of passengers (500) to estimate the energy used per person.
Energy used per person = Energy consumption / Number of passengers
Energy used per person = 1,412,795 MJ / 500
Energy used per person = 2,825.59 MJ
Finally, we convert megajoules (MJ) to joules (J) by multiplying by 1 million:
Energy used per person = 2,825.59 MJ * 1,000,000 J/MJ
Energy used per person = 2,825,590,000 J
The estimated energy one person uses in one round-trip from Phoenix to London to Phoenix is approximately 2.5 million joules (2,825,590,000 J).
Keep in mind that this is a rough estimation and the actual energy usage may vary depending on various factors such as aircraft efficiency, load factors, and operational practices.
