C.V. (kcal/Nm3) of gaseous fuels _____________ with increase in molecular weight?
Correct answer: D. May increase or decrease, depends on combustibles
- A. Decreases
- B. Increases
- C. Remain constant
- D. May increase or decrease, depends on combustibles
Explanation
Calorific value per normal cubic metre depends on the combustible gases present, not on molecular weight alone. Therefore, increasing molecular weight may raise or lower the volumetric calorific value depending on the gas composition.
