If 10 kg of a fuel X produces 1,60,000 J of heat on complete combustion then, the calorific value of X in `Kj//kg` is _________.

Text Solution

Verified by Experts

The correct Answer is:
16

10 kg of X produces heat = 1,60,000 J
1 kg of X will produce heat `= 1,60,000//10 J`
`= 1,6000 J = 16 kJ`
Hence, calorific value of fuel X `= 16 kJ//kg`
