A sample of refuse has a moisture content of 20%. A 1.2 g sample is placed in a calorimeter, and a gross calorific value of 14,400 kJ/kg is measured based on the temperature rise. Further analysis shows that .3 g of ash remains in the bomb calorimeter after combustion. Calculate the HHV in terms of (a) moisture-free and (b) moisture- and ash-free
