Answer to Question #126402 in General Chemistry for Nabel Dimaampao

Question

During the determination of calorific value of a gaseous fuel by Boy’s
calorimeter, the following results were recorded:

Volume of gaseous fuels burnt at NTP = 0.098 m3
Weight of water used for cooling the combustion products = 50 kg
Weight of steam condensed = 0.051 kg
Temperature of inlet water = 26.1 °C
Temperature of outlet water = 46.5 °C
Latent heat of condensation of steam = 587 kcal/kg
Determine the gross and net calorific values.

Answer 1

Volume of gaseous fuels burnt at NTP = 0.098 m3

Weight of water used for cooling the combustion products = 50 kg

Weight of steam condensed = 0.051 kg

Temperature of inlet water = 26.1 °C

Temperature of outlet water = 46.5 °C

Latent heat of condensation of steam = 587 kcal/kg
