Question :
A sample of coal containing the following elements:C=90%; H=5%; ash=4%; weight of the coal burnt=0.90g; weight of the water taken=600g; water equivalent of bomb calorimeter=2000g; rise in temperature=2.48oC; fuse wire correction=10cal; cooling correction=0.02oC; acid correction=50 cal. Calculate net and GCV of coal in cal/g. Assume latent heat of steam is 580cal/g.
1. HCV=7155.55cal/g; NCV=6894.55cal/g
2. HCV=6894.55cal/g: NCV=7155.55cal/g
3. HCV=7171.2cal/g; NCV=6889.2cal/g
4. HCV=6889.2cal/g; NCV=7171.2cal/g
Answer :
1 - HCV=7155.55cal/g; NCV=6894.55cal/g
