Question

calculate calorific value of a fuel if heat produced on complete burning of 20 kg of a fuel in pure oxygen is 100 KJ ??​

Answer 1

Answer: Total mass of fuel = 20kg

Total heat produced = 100kJ

Heat produced by burning 1 kg of fuel =100 kJ/20 kg

= 5 kJ/kg.

so, calorific value of fuel is 5 kJ/kg

$\boxed{\fcolorbox{black}{yellow}{Calorific value = 5 kJ/kg}}$

hope it helps ✌️
