Question

If an expirement 5kg of fuel completely burns to produce 1,80,000 kj of heat energy which among the foloowing is its calorofic value a)40,000 kj b)35,000kj c)36,000kj d)45,000kj

Answer 1

Answer:

36,000 KJ / Kg

Explanation:

Calorific value is the amount of heat energy released on complete combustion

of 1 kg of a fuel.

Unit : kJ/kg

Calculation:

Given data:

Weight of the fuel = 5 kg

Heat produced = 180000 kJ

To find:

Calorific value = ?

Formula:

Calorific value = heat produced / weight of fuel used in Kgs

Calorific value     = 180000/ 5

                          = 36000 kJ/kg
