Question

The calorific value of kerosene is 45000 KJ/Kg What is the mass of kerosene to be taken to produce energy of 27,00,000 KJ/kg

Answer 1

Answer:

Explanation:

Calorific energy = Energy / mass

            45,000  =  27,00,000 / Mass required

                 Mass = 27,00,000 / 45,000

                 Mass = 60 Kg

Answer 2

Answer:

The mass of the kerosene to be taken is 60 Kg.

Explanation:

The formula for calorific value is given as,

$calorific \: value = \frac{amount \: of \: heat \: produced}{mass \: of \: the \: element}$

$c = \frac{e}{m}$

c = 45,000 KJ/Kg

e = 27,00,000 KJ/Kg

m = ?

$45000 = \frac{2700000}{m}$

$m = \frac{2700000}{45000}$

$m = 60 \: kg$
