In a bomb calorimeter experiment, following data was obtained: x = 0.85gm, W = 2.5kg, w = .5kg, observed rise in temperature = 2.25 0C, tA = 38.6 calories, tF = 6.8 calories, tT = 1.9 calories and tC = 0.05 0C. Calculate net calorific value if the coal contains 10 % hydrogen?

In a bomb calorimeter experiment, following data was obtained: x = 0.85gm, W = 2.5kg, w = .5kg, observed rise in temperature = 2.25 0C, tA = 38.6 calories, tF = 6.8 calories, tT = 1.9 calories and tC = 0.05 0C. Calculate net calorific value if the coal contains 10 % hydrogen? Correct Answer 7533.7 cal/gm

From the formulae, GCV = /x GCV = 8062 cal/gm NCV = GCV – (0.09×587×%H) NCV = 7533.7 cal/gm.
