Hydrogen content in petroleum products varies from 12 to 15% (by weight). As a result the difference between gross and net heating value of petroleum fuels varies in the range of ______________ kcal/kg?
Correct answer: A. 600-750
- A. 600-750
- B. 250-350
- C. 1000-1500
- D. 2000-2500
Explanation
The gross-to-net heating-value difference mainly represents the latent heat of vaporising water formed from hydrogen combustion. With 12 to 15% hydrogen, this loss is approximately 600 to 750 kcal per kilogram of fuel, so option a fits.
