![4. A 0.72 g of a fuel containing 80% carbon when burnt in a bomb calorimeter, increased the
temperature of water from 27.3 °C to 29.1 °C. If the calorimeter contains 250g of water and its
equivalent is 150 g, calculate the HCV (higher calorific value) of the fuel in kJ/kg.
5. On burning 0.83 g of a solid fuel in a bomb calorimeter, the temperature of 3500g of water
increased from 26.5 °C to 29.2 °C. The water equivalent of calorimeter and the latent heat of
steam are 385.0 g and 587.0 cal/g, respectively. If the fuel contains 0.7% hydrogen, calculate the
GCV and NCV.
6. Liquid fuel weighing 0.98 g and contains 90.1% C, 8% H with the following results in bomb
calorimeter experiment:
Amount of water taken in calorimeter = 1450 g
Water equivalent of calorimeter = 450g
Rise in temperature of water = 1.8 °C
If the latent heat of steam is 587 cal/g, calculate the gross and net calorific value.
