Question

after burning 5kgs of fuel, the heat produced waa measured as 275,000kj. calculate the calorific value of fuel.​

Answer 1

Given that:

⇒After Burning 5kg Of Fuel, The Heat Produced Wal Measured As 2,75,000 Kg. Calculate Of The Calorific Value Of Fuel

To Find:

⇒The Calorific Value Of Fuel

$\begin{gathered}\large\underline{{\text{Required Answer:-}}} \\\end{gathered}$

• In an experiment 5 kg of a fuel was completely burnt, the calorific value of the fuel for the heat produced measured to be 200,000 kJ is 40,000 kJ/kg.

➙Total mass of fuel in the experiment = 5 kg

➙Total heat produced in the experiment = 200,000kg

➙Heat produced by burning 1 kg of fuel can be expressed as,

200,000 kJ/5 kg = 40,000kg.

Hence,

Calorific value of fuel is given by 40,000 kJ/kg.

Answer 2

Answer:

➙Total mass of fuel in the experiment = 5 kg

➙Total heat produced in the experiment = 200,000kg

➙Heat produced by burning 1 kg of fuel can be expressed as,

200,000 kJ/5 kg = 40,000kg.

Hence,

Calorific value of fuel is given by 40,000 kJ/kg.
