Answer:
family consumes 12kg of L.P.G in 30 days. What is the average energy consumed per day if the calorific value of L.P.G is 50kj/kg?
Calorific value of LPG = 50 kj/kg
family consumes 12 kg of L.P.G in 30 days
Calorific value of 12 kg of LPG
= 50kj/kg × 12 kg
= 600 kj/kg
600 ki/kg energy consumed in 30 days. Thus
Average energy consumed per day
= 600/30
= 20 kj/kg
Answer the family consumes 20 kj/kg energy.
