What is the amount of heat when calorific value is 150000 and amount of fuel is 5

Given: The calorific value =  150000KJ

Amount of fuel used = 5kg

To find: We have to find the amount of heat generated.

Solution: From the question, we can find that 1kg of fuel can produce 150000 joules of heat. Therefore 5 kg of fuel can produce 150000 x 5 = 750000 joules of heat.
