The ultimate analysis of bituminous coal (dry basis) is: C=77%; H=5.8%; N=1.7%; O=4.8%; S=2.5%; and ash=9.0%.

The moisture content is 5%. Calculate using Dulongs formula.

(a) Gross calorific value, moist basis
(b) Net calorific value, moist basis
(c) Gross calorific value, dry basis
(d) Net calorific value, dry basis
