Ответ:

Для розрахунку кількості теплоти, яку можна отримувати щодня при сжиганні газа, спочатку розрахуємо кількість газу, яка споживається щодня.

За даними месторождення, річний видобуток газу дорівнює 261,6 млрд кубометрів. Щоб отримати щоденний обсяг видобутку, розділімо це число на 365 днів:

261,600,000,000 куб. м / 365 днів ≈ 717,808,219.18 куб. м/день

Тепер ми знаємо, що щоденно видобувається приблизно 717,808,219.18 кубометрів газу.

Далі розрахуємо кількість теплоти, яку можна отримати при сжиганні цього газу. Використовуємо дані:

- Плотність газу (ρ) = 1,2 кг/м³

- Удельна теплота сгорання газу (Q) = 50 МДж/кг

Спочатку перетворимо удельну теплоту сгорання в Дж:

50 МДж = 50 * 10^6 Дж/кг

Тепер можемо розрахувати кількість теплоти (Q) для щоденного видобутку газу:

Q = (кількість газу) * (удельна теплота сгорання)

Q = 717,808,219.18 куб. м * 1.2 кг/м³ * 50 * 10^6 Дж/кг

Обчислімо це:

Q ≈ 4.32 * 10^15 Дж/день

Отже, щоденно можна отримувати приблизно 4,32 * 10^15 Дж теплоти при сжиганні цього газу.
