Dulong's Formula

Dulong's Formula According to dulong's Formula, Gcv=1/100[8080 c + 34500 (H-0/8) + 2240S] kcal kg–¹ Where C,H,O,S refer to % of carbon , hydrogen, oxygen and surphur respectively. Ncv=Gcv - latent heat of water vapour formed. =Gcv - Mass of hydrogen × a × latent heat of steam since 1 part by mass of hydrogen produces 'a' part by mass of water.
