Questions and Answers

According to Dulong's formula, what is the equation to calculate the higher heating value of a fuel?

  • AS Higher heating value = 33.7 C + 144 ( W.2-— ) +9.3 S 8
  • AS Higher heating value = 33.7 C + 144 ( W.2-— ) +9.3 S 8 02N
  • AS Higher heating value = 33.7 C + 144 ( W.2-— ) +9.3 S (correct)
  • AS Higher heating value = 33.7 C + 144 ( W.2-— ) +9.3 S 02N
