How many man hours of energy will one barrel of oil produce?

Calculation:

1 barrel of oil energy: 6.1 GJ = 1691.8 kWh

Energy per hour: 1691.8 kWh / 24 hours = 70.49 kWh/hour

Explanation:

One barrel of crude oil contains about 6.1 GJ of energy. To calculate the number of man hours of energy produced by one barrel of oil, we need to convert GJ to kWh. 1 GJ is equal to 278 kWh, so 6.1 GJ is equal to 1691.8 kWh.

Now, we need to calculate the number of man hours. Let's assume that one person works for 8 hours a day. In a year, there are approximately 365 days. So, in total, one person works for 2920 hours (8 hours/day x 365 days).

Therefore, one barrel of oil can produce approximately 0.58 kWh of energy per hour. This means that in total, one barrel of oil can produce around 1691.8 kWh of energy, which is equivalent to 2920 man hours of energy.
