Question

If calorific value of a fuel is 10,000 kj/kg ,how much of this fuel is required to produce 25,000 kj of energy ​

Answer 1

Answer:

In literature the net calorific value of the fuel is obtained by subtracting from higher calorific value the amount 2466 kJ/kg (latent heat of dry and saturated steam at STP (15°C) conditions) (amount of water formed because of the combustion of 1 kg fuel.)

Answer 2

Answer:

2.5 kJ

Explanation:

Calorific value=Amount of energy/Amount of fuel

Let amount of fuel be X

10,000 = 25000/X

X= 25000/10000

X= 25/10

X=2.5 kJ
