A coal sample contains C = 90%; H = 9%; and ash = 1%. When this coal sample was tested in the laboratory for its calorific value in a bomb calorimeter, the following data were obtained: Weight of coal burnt = 0.75g Weight of water taken = 820g Water equivalent of bomb calorimeter = 1500g Temperature increase = 2.8°C Fuse wire correction = 10 cal Cooling correction = 0.07°C Acid correction = 90cal Calculate the gross and net calorific value of the coal sample in cal/g. Assume the latent heat of condensation of steam as 580 cal/g
